Question

calculate the relative molecular mass
Zn 03 b) CaSO4 c)
CO2)2 d) (NH4)2Cro7 e)
CuSO4.5H20​

Answer 1

Answer:

option d is ur answer bro (NH4)2Cro7

explanation

The relative molecular mass/relative formula mass is defined as the sum of all the individual atomic masses of ALL the atoms in the formula (Mr). e.g. for ionic compounds e.g. NaCl = 23 + 35.5 58.5) or molecular mass for covalent elements or compounds ...

Answer 2

Answer:

Molar mass of CuSO4.5H2O = 249.685 g/mol

Convert grams CuSO4.5H2O to moles  or  moles CuSO4.5H2O to grams

Molecular weight calculation:

63.546 + 32.065 + 15.9994*4 + 5*(1.00794*2 + 15.9994)
