Answer to Question #85963 in General Chemistry for melanie

Question

What is the volume of a sample of helium that has a mass of 7.42 × 10−3 g, and a density of 0.17847 g/L?
Answer in units of mL.

Answer 1

m= d*V

V = m/d = 7.42*10^-3/0.17847 g/L = 0.0416L

As 1 L = 1000 mL , then V = 0.0416 L *1000mL/L = 41.6 mL

Answer: 41.6 mL
