Answer:
Hope it helps you...☺☺☺
Explanation:
(i) Molar mass of Cu = 63.5
Molar mass of S = 32
Molar mass of O = 16
MOLAR MASS OF CuSO4 = 63.5+32+4(16)
M = 159.5 amu
(ii) Molar mass of Ca = 40.08
Molar mass of Cl = 35.45
MOLAR MASS OF CaCl2 = 40.08 + 35.45 + 35.45
M = 110.98 amu
(iii) Molar mass of N = 14
Molar mass of O = 16
MOLAR MASS OF NO2 = 14+16(2)
= 14+32
M = 46 amu
(iv) Molar mass of H = 1
Molar mass of S = 32
Molar mass of O = 16
MOLAR MASS OF H2SO4 = 2(1)+32+4(16)
M = 98 amu
