Question

1.0g of metal nitrate gave 0.86g of metal sulphate .calculate the equivalent weight of the metal

Answer 1

Equivalent valen weight of nitrate = 62
Equivalent weight of sulfate = 48
Equivalent weight of metal = E

Equivalent weight of metal nitrate = Equivalent weight of metal sulfate
1/(E + 62) = 0.86 / (E + 48)
48 + E = 0.86E + 53.32
E = 38

Equivalent weight of metal is 38

Answer 2

Answer: Equivalent weight of metal is 38g

Explanation: To calculate the equivalent weight of metal we need to equate:

$W_{MNO_{3}}/E_{MNO_{3}}=W_{MSO_{4}}/E_{MSO_{4}}$

The valency of nitrate is 1 and the valency of sulphate is 2, So the equivalent weight is as given below:

$Equivalent\ weight\ of nitrate=62/1=62\\Equivalent\ weight\ of\ sulphate=96/2=48\\1/(E+62)=0.86/(E+48)\\0.14E=5.32\\E=38$
