Question

What is the mass of the ethyl alcohol that exactly fills a 200.0 mL container? The density of ethyl alcohol is 0.789 g/mL. Give your answer in grams, round to the whole number *

Answer 1

Explanation:

mass = density*volume = 0.789*200

= 157.8 grams = 158 grams

Answer 2

The mass of ethyl alcohol is 158 grams.

Given - Volume and density

Find - Mass

Solution - Density = mass/volume

Keep the values in formula to find mass.

Mass = Density*Volume

Mass = 0.789*200

Performing multiplication

Mass = 157.8 grams

Rounding off the mass

Mass = 158 grams

The mass of ethyl alcohol is 158 grams.
