Hi, so over here we need to multiply or divide the following measurements, ensuring that we're going to put the correct number of significant digits.
00:06
So, in this case, remember that for multiplication and division, we're going to keep as many significant digits or significant figures as the number or the measurement with the least amount of them.
00:18
So, in the first case, we're going to have 5 significant figures versus 5 significant figures, for which the result should have as well 5 significant figures.
00:29
So, after rounding up this number with the correct amount, we're going to end up with 5 .3273 mol per liter on the first scenario.
00:42
For the next quantity that we're going to consider, we have a number with 5 significant figures versus another one with 2 significant figures, thus our result should have 2 significant figures as well.
00:54
In this case, we're going to require to employ scientific notation, the result without rounding it up is going to be 822 .85185185.
01:09
It is going to be a periodic number, but in this case we require only two significant figures.
01:14
That means that we need to cut it up to this quantity...
