Question

What is the mass, in grams, of 28.42 mL of acetone?

Answer 1

V = 28,42 mL = 0,02 L
molar mass C3H6O = 58


n C3H6O
= V / 22,4
= 0,02 / 22,4
= 0,0009 mol


mass
= n x molar mass
= 0,0009 x 58
= 0,0522 gr

Answer 2

22.48 grams.

Step-by-step explanation:

In order to calculate this you just need to remember the formula for the density of materials, the density of Acetone is: 0.791 g/mL

So in order to calculte the mass we just use the next formula:

Density= mass/volume

Remember that mililiters is a unit for vulome:

Mass= Volume*density

We insert the values:

28.42*0.791ml=22.48 grams

So the mass og 28.42 mililiters of acetone will be 22.48 grams
