Answer 2

Dear Student,

◆ Answers -

(a) 16 g

(b) 124 g

(c) 16 g

● Explaination -

(a) 6.02×10^23 atoms of oxygen -

Mass of oxygen is -

W = M × n

W = M × N / NA

W = 16 × 6.02×10^23 / 6.02×10^23

W = 16 g

(b) 6.02×10^23 molecules of P4 -

W = M × n

W = M × N / NA

W = 124 × 6.02×10^23 / 6.02×10^23

W = 124 g

(c) 3.01×10^23 molecules of O2 -

W = M × n

W = M × N / NA

W = 32 × 3.01×10^23 / 6.02×10^23

W = 16 g

Thanks dear. Hope that was helpful...
