Question

find the no. of atoms in 124 gr of p4 molecule

Answer 1

there are 4 P / 1mole of P4; each P weighs 31 

124 g P4/31 g/mole P = 4 moles of P; 1 mole of P4 


6.02 E23 P4 
2.41 E24 P atoms

Answer 2

there are 4 P / 1mole of P4; each P weighs 31 

124 g P4/31 g/mole P = 4 moles of P; 1 mole of P4
