Calculate the mass of 20 moles of acetone C2H2.
| July 15, 2021 | education
The mass of a substance can be found by the formula: m = v * M (v = 20 is the amount of substance, which is measured in mol, M is the molar mass, which is measured in grams per mole (g / mol)).
You need to find the molar mass of acetone.
M (C2H2) = 12 * 2 + 1 * 2 = 26 g / mol.
12 is the molar mass of carbon, 1 is the molar mass of hydrogen (from the periodic table of chemical elements).
The mass of acetone will be equal:
m = 20 * 26 = 520g.
Answer: 520 grams of acetone.
