Question

the no. of molecules in 5.65 g of ammonia is approx X into 10^23.what is the value for X..Plz ans with full explanation. ​

Answer 1

Given mass (g)= 5.65 g

Molar mass of ammonia (m)=17.031

Moles =given mass/molar mass

Moles =5.65/17.03

Moles×avagadro number = number of particle

5.65/17.03×6.022×10(23)=x10(23)

3402.43/1703×10(23)=x10(23)

1.99= x

Hope it helped
