CH2 , molar mass =84g/mol. If you add the atomic masses of one C and two H you get 12+2×1=12+2=14. That goes 6 times into 84, so multiply the numbers of each atom times 6 to get C6H12 as the formula for the compound with molar mass 84.Feb 16, 2019 · Molar mass of the compound is . 24 + 5.04 + 14 + 32 = 75.04 g/mol, so 0.00306 g is 0.04078 millimoles. Then there are 5 x 0.04078 mmol of H atoms, that is 0.2039 mmol of H atoms, or 0.000204 moles of H atoms, or 0.000102 moles of H2 ("hydrogen"). It's not clear whether they want moles of H atoms or moles of H2 molecules.

Molar mass and elemental composition calculator. Relative atomic masses are expressed with five significant The molar mass of a substance (M) is the weight of one mole of the substance. When the formula contains no carbon, all the elements, including hydrogen, are listed alphabetically.Calculating Molar Concentrations from the Mass of Solute Distilled white vinegar (Figure 2) is a solution of acetic acid, CH 3 CO 2 H, in water. A 0.500-L vinegar solution contains 25.2 g of acetic acid.

#molarmass_(C_2H_5NO) = 24.0 + 15.0 + 16.0 + 5.00=59# g/mol. The final step to determining the molecul's mass percent is to divide each elemnt's contribution by acetamide's molar mass and to multiply the result by 100%.
