Part D Now that the power of is the same in both figures, you can just look at the first factors of each figure. So, how many ti
mes smaller or larger is the first factor of the mass of an average grain of table salt than the first factor of the mass of an average grain of rock salt?
From part D, the mass of an average grain of rock salt is 120 x 10^-4. The first factor is 120.
The mass of an average grain of table salt is 3 x 10^-4. The first factor is 3. Let x times the first factor of the mass of an average grain of table salt be equal to the first factor of the mass of an average grain of rock salt.
3x = 120
x = 120/3
x = 40
So, the first factor of the mass of an average grain of rock salt (120) is 40 times the first factor of the mass of an average grain of table salt (3).
