So in this question, we're going to calculate the volume of substance, and we're going to follow the four -step method for basic steps.
00:08
So first we're going to analyze.
00:10
We are given, first we're given the mass, we are given the mass of 2 .03 times 10 to the negative 3 grams.
00:26
But then we're also given the density of 9 .133 times 10 to the 9 .1 .33 times 10 to the 9.
00:32
Negative 1 per centimeter cubed, which we can use as a conversion factor.
00:36
So i'm going to set it up already as a conversion factor so that one centimeter cubed will contain 9 .133 times 10 to the negative 1 grams.
01:00
Now if we, so now we can convert this.
01:03
We find that our units cancel, and we are left with centimeters cubed.
01:10
So our final answer is 0 .002.
01:20
So see, we executed, we analyzed, we found that we needed to find the volume.
01:27
I can't forget the unit centimeters cubed.
01:31
We found the volume.
01:32
We needed to plan.
01:33
We planned that we were going to convert from growth.
01:36
Grams here.
01:36
I'll write the plan over here, grams, into centimeters cubed.
01:44
And then we computed...
