Question

calculate the number of particles in 6.9 g of znso4 give answer step by step with working
​

Answer 1

Explanation:

molecular weight of ZnSO4 is 161g .

for 161g avagadro number of particles are present .

for 6.9g of ZnSO4 avagadro 6.9 avagadro number / 161 particles are present .

this is approximately equal to avagadro number / 7.

substitute 6.023 × 10²³ in placs of avagadro number gives answer .
