Ok so this is the final question to my homework, and I cannot get this question wrong. I think I know the correct answer but I want to be 100% sure. Now I know this may be an easy question to most of you guys, so don't make fun of me too much.


A sample of iron has a volume of 10.0 mL. The density of iron is 7.87 g/mL. Which is the correct expression to calculate the mass of the sample using dimensional analysis?

Here are the choices.

10.0 mL × (7.87 mL/1 g)
10.0 mL × (1 mL/7.87 g)
10.0 mL × (1 g/7.87 mL)
10.0 mL × (7.87 g/1 mL)

Thanks in advance.
