Answer:
number of molecules = 1.8 x 10²⁴
Explanation:
number of molecules = number of moles x 6 x 10²³
- we have to find number of moles in order to find the number of molecules.
mole = mass given/ molar mass (Mr) (mass=51g , and Mr= 14 + 3 = 17 g/mol)
= 51/17 = 3 mol
- now apply the formula for finding number of molecules.
no. of molecules= no. of moles x 6 x 10²³
= 3 x 6 x 10²³
= 1.8 x 10²⁴
