Calculate the molar mass of each compound.
СН:
g/mol
C, H3,03
g/mol
g/mol

13.0186g/mole

63.0326g/mole

Explanation:

Given parameters;

Compounds - CH

                       CH₃O₃

To solve this problem, let us delve a bit into molar mass of a substance;

The molar mass of a substance (atom or molecule or compound) is the mass in grams of one mole of the substance.

Simply add the component atomic masses to find this number;

Atomic mass of Carbon = 12.0107g/mole

                          Hydrogen  = 1.0079g/mole

                          Oxygen    = 15.9994g/mole

Molar mass of CH  = 12.0107 + 1.0079 = 13.0186g/mole

Molar mass of   CH₃O₃ = 12.0107 + 3(1.0079) + 3( 15.9994) = 63.0326g/mole

the right answer is 0.3 meters per second
