Question

The molar mass of tartaric acid is 150,empirical formula mass is 75,the 

   empirical formula is------​

Answer 1

Answer:

Empirical formula weight = (1 x 12.01g/mol) + (2 x 1.01g/mol) + (1 x 16.00g/mol) = 30.02g/mol.

Divide the molar mass for the molecular formula by the empirical formula mass. The result determines how many times to multiply the subscripts in the empirical formula to get the molecular formula.

hope it helps you good day!!

Answer 2

${\huge{\boxed{\mathtt{\pink{ANSWER  :-}}}}}$

The molecular formula H2O2 is a multiple of the empirical formula. We can know this because the ratio of 2H:2O is not the lowest whole number ratio. By dividing the subscripts by 2 , we can determine the lowest whole number ratio, which is 1H:1O . Therefore, the empirical formula for H2O2 is HO .
