Calculate the mass in grams of 69.9 mL of diethyl ether, an anesthetic that has a density of 0.713 g/mL

significant figures.

. Be sure your answer has the correct number of
mL

Answer 1

To calculate the mass of 69.9 mL of diethyl ether, we would multiply the volume by the density of the substance:

Mass = Volume x Density
Mass = 69.9 mL x 0.713 g/mL
Mass = 49.8387 g

Since the original volume was given to three significant figures, the final answer should also be rounded to three significant figures:

Mass = 49.8 g
