Cyclopropane, C3H6, is an anesthetic given by inhalation. How many grams are in 0.23 moles of cyclopropane?
Express your the mass in grams to two significant figures.

9.7 g C3H6

Explanation: To find the mass of cyclopropane C3H6, we will use the relationship of 1 mole of cyclopropane is equal to its molar mass.

The molar mass of C3H6 is 42 g C3H6.

0.23 mole C3H6 x 42 g C3H6 / 1 mole C3H6

= 9.7 grams C3H6
