Okay, so here we&#x27;re looking at, um, percentage ever. So let&#x27;s take a look at, uh, the equation to calculate percentage area, so percent error, 4% e abbreviate. It is equal to, um, your experimental out value. So value experimental. Yes, P um minus you&#x27;re accepted Value a C c. Divided by, uh, the accepted value. And this is all multiplied by 100%. There is a condition under which percentage error can be negative, and that&#x27;s if the accepted value is larger than the experimental, and that&#x27;s that.

Hello. So today we&#x27;re going to be solved in question Number 49 where we find the bail on percent, Ella in our experimental values from question number 47. So I did. I&#x27;ve given you the percent error and off to the side and green. I&#x27;ve written our accepted values. So now all we have to do with Global my uncle always into the equations and solved. The first song is the me says. But now we have to do with Saul. That leaves us there. And a percent error of 0.0 12307%. All right. Moving on to our second value. Okay. Our 2nd 7 which gives a 0.2. Aaron, I love zero point 2615%. All righty. Moving on toe, which is our third experiment, which leave Clinton going one and a person. 07%. I hope that helped

Okay, so this problem wants you to calculate the percent errors for all of student these trials. So we know that percent error is given by this equation where the absolute value of the error is divided by the accepted value, which in this case is 1.59 Make this red. So 1.59 is your accepted value. All of your errors. You are going to be in this column here and in order to make this into a percentage, your room to multiply this by 100. So student be had three trials. So for trial number one in order to calculate the percent error So the do percent error is equal to 100 times the error, which is negative 0.19 grams per centimeters cubes divided by the accepted value, which is 1.59 grams per centimeters. Cute. And because this is absolute value, this is going to become a positive number. And so there&#x27;s going to be your percentage is going to be a positive number. So if you multiply this out or divide this out, you&#x27;re going to get a percentage of 11.95 person error for trial. One pretrial, too. We just do the same thing where percent and is going to be equal. Thio 100 times. No, it&#x27;s plus 0.9 grams per centimeters. Cute divided by 1.59 centimeter is cute. And when you multiply that you get a percent error of 5.66 percent and for trial number three will destroy this. Over here, you&#x27;re percent error is going to be percent. Error is going to be 100 times trial three&#x27;s air, 0.14 grams per centimeter Acute. Yeah, divided by your accepted value, which again is 1.59 grams per centimeter. Cute. And so when you multiply this out you get a percentage of 8.1 a 0.81%. So now if you look back at these original errors because we only care about the overall value, the absolute value, we don&#x27;t care about whether it&#x27;s greater value or lesser value. So just to see if our answer&#x27;s kind of makes sense, you can see that Trial one has the largest error. So we would expect there to be the largest percent error. So 11.95 is our largest percent error trial to has our lowest error. So we would expect this value time, our lowest percentage value as well. And Trial three has a value that somewhere in the middle so you can see the 8.1% is somewhere in between 11.95% in 5.66% so our math and our answers make sense.

Okay, so we have an experimental mass value of 9.67 grams. Uh, however, the accepted value is 9.82 grands, and we want to find the percent error between these. So recall of that percent error equals, um uh, he accepted value. I&#x27;m sorry. The experimental value minus accepted over the accepted value times 100%. So just putting in, um, our values here, respectively. So we have 9.67 gram minus 9.8 two grams. This is all divided by the except value 9.8 two grams times 100%. Once we plug and chug, we should get minus 1.53% error. Um, which means that this experimental value is 1.53% lower than the accepted value. That&#x27;s that.

came today and I&#x27;ll be gone over questioning their 32 trans Lou talking person here. First it&#x27;s stringers leading saw. The heirs are for trial. One trying to try all three. You&#x27;re the air wells. Make it in way 19. Okay? Because the furniture you like tea this year here to was less than only three waas my point for So in order to calculate the percent here you do the absolute one undermined by your no, by 100 you. So it doesn&#x27;t point person here. Trial one Carol choose by 0.6 Trump three is a equipment.
