Did I Calculate the Volume and Density Correctly?

[bedizzy]

Question:

The mass of a container filled with liquid mercury is 244.0 g, and the mass of the empty container is 110.2 g

a. What is the volume of the container? (density of mercury = 13.546 g/ml)

b. The same container is filled with a second liquid, and the mass of the filled container is 114.9 g. What is the density of the second liquid?


My answers:

a)

244.0 g - 110.2 g = 133.8 g
133.8 g/(13.546 g/mL) = 9.877 mL


b)

114.9 g - 110.2 g = 4.7 g
4.7 g/9.877 mL = 4.8x10 g/mL



Does that look right? if not where did I go wrong?

I appreciate the help...

Looks fine to me!
