Answer 1

option D. 4.0

Explanation:

Mass Volume

Sample 1 0.65 0.5

Sample 2 5.2 x

`(0.65)/(5.2) = (0.5)/(x)\\\\0.65 * x = 0.5 * 5.2\\\\0.65x = 2.6\\\\x =(2.6)/(0.65) =4`

Answer 2

4.0.

Explanation:

In sample 1, you do 0.65/1.3 which gets you to 0.5, so then you do the same to the bottom which you also have to divide by 1.3, and 5.2/1.3 is 4.0 or 4.
