Asked Sep 11, 2019

A 25-mL pipet sample of an alcohol is found to weigh 20.71 g. What would be the mass of 35.25 mL of the same alcohol? What volume would be occupied by 125.4 g of this alcohol?

Step 1

Given that,

Weight of alcohol sample = 20.71 g

The volume of alcohol sample = 25 mL

So, density can be calculated by using the formula,

Substitute the values in equation (1) to calculate the density as follows:

Step 2

Now, volume of same alcohol = 35.25 mL

Calculated density = 0.8284 g-mL-1

Mass can be calculated by ...
