Answer to Question #131600 in General Chemistry for Britlynn Lee

Question

The density of butane, C4H10 , is 2.49×10−3 g/mL . Calculate the number of moles of butane in a 35.9 mL sample.

Answer 1

 2.49×10⁻³ g/mL × 35.9 mL = 0.089391 g

Butane molar mass 58.124 g·mol−1

0.089391 / 58.124 g·mol−1 = 0.001538 mol
