Answer:
37.6 grams of pentane
Explanation:
The density given in the CRC of 0.626 g/cm³ will be used to calculate the mass of pentane requred since Density = m/v and m= D x V
Be careful in this kind of questions to check for the units. In this case one has to remember 1 mL equal 1 cm³.
m = 0.626 g/cm³ x 60.0 cm³ = 37.6 g pentane
