Acompound has the formula ch3co2h. r how should the relative molecular mass, mr, of this compound be calculated? a 12 1 16b 3(12 1) 2(12 16) 1c (4 x 12) (2 x 1) 16d (2 x 12) (4 x 1) (2 x 16)

Carbon has a Molar Mass of 12, Hydrogen has a Molar Mass of 1 and Oxygen has a Molar Mass of 16.

Acetic Acid has 2 Carbon atoms, 4 Hydrogen atoms and 2 Oxygen atoms.
Therefore, to calculate relative molecular mass all we need to do is:

2*12 + 4*1 + 2*16 = 60 g/mol

You would do 1500/4 and the answer is 375
