Calculate the mass in grams of 56.2ml of diethyl ether, an anesthetic that has a density of 0.713 g/ml . Be sure your answer has the correct number of significant figures.

To calculate the mass of diethyl ether, we can use the formula:

mass = volume x density

Given that the volume is 56.2 ml and the density is 0.713 g/ml, we can substitute these values into the formula:

mass = 56.2 ml x 0.713 g/ml = 39.9736 g

Rounding to the correct number of significant figures, the mass of 56.2 ml of diethyl ether is 40 g.
