Question

Calçulate the no of atoms 16 u of he

Answer 1

No of atoms = n

Given mass = m

Molar mass = M

Given number of particles = No

Atomic mass of he = 4u

Molar mass of he = 4g

Thus, the number of mass

=given mass

molar mass

= n =m/M =16/4 = 4 ans

I HOPE THIS IS HELP U ==================== ✌️✌️✌️
