Question

Calculate the no. Of particles in 31g of P4 molecules

Answer 1

Answer:

1.55* 10^23 particles (approx)

Explanation:

molar mass of P = 31g

molar mass of P4 molecule = 4*31 = 124g

1mol of P4 = 124

x mol of P4 = 31

x = 1/4

1mol = 6.022 * 10^23

1/4 mol = 1/4*6.022*10^23

= 1.55* 10^23 particles (approx)
