Question

calculate molecular mass for the following
1. Sodium hydrogen carbonate
2. Ammonium chloride
3. Calcium sulphate
4. Hydrogen sulphide
5. Magnesium nitrate
Atomic mass C-12u, N-14u, Mg-24u, S-32u, H-1u, O-16u, Ca-40u

Answer 1

Explanation:

1.NaHCO3:-23+1+12+16(3)

23+13+48=84g

2.NH4Cl

14+1(4)+35

14+4+35=53g

3•CaSO4

40+32+16(4)

40+32+64=136g

4.H2SO4

2+32+16(4)

34+64=98g

5.Mg(No3)2

24+28+96=148g

I hope this answer is useful for youuu.....
