Question

Calculate the mass persent of different element in Sodium sulphate.

40, 20, 40
20, 60, 20
30, 60, 10,
32, 22, 45​

Answer 1

Answer:

d. 32 22 45

Explanation:

Na2SO4

total mass will be 2Na+S+4O

=2*23+32+4*16

=46+32+64

=142

Mass percent of element

=given mass of element/total mass of compound*100

Na: 46/142*100=32%

S: 33/142*100=22%

O: 64/142*100=45%
