How do you know that volume of a diamond is 15.1g
marshall27 [118]

Answer:

Density = mass / volume,  

        therefore volume = mass / density. Note that 1 mL = 1 cubic centimeter.

Explanation:

Volume = 15.1g / 3.52g/mL = 4.3mL = 4.3 cubic centimeters.

then a  diamond has a density of 3.52 g/mL.

What is the percent by mass of carbon in acetone, c 3 h 6 o?
Tatiana [17]
In the problem, we are tasked to solved for the amount of carbon (C) in the acetone having a molecular formula of C 3 H 6 O. We need to find first the molecular weight if Carbon (C), Hydrogen (H), Oxygen (O).

Molecular Weight:
C=12 g/mol
H=1 g/mol
O=16 g/mol

To calculate for the percent by mass of acetone, we assume 1 mol of acetone.
%C=( \frac{3(12 g/mol)}{3(12 g/mol)+6(1 g/mol)+16 g/mol} ) x 100%
%C=62.07%
Therefore, the percent by mass of carbon in acetone is 62.07%
