Question

The mass of one molecules of Phosphorus (P-31) is
(A) 31 g
(B) 2.059 x 10-22 g
(C)5.147 x 10-23 g
(D) 124 g​

Answer 1

Answer:

The Answer is on the Sheet. This is for P4. If you want to take P31, Then Molar mass of P31 is 960. Now then Replace the 31 with 960 and do the Calculations . Your Answer will be 1.5 × 10 the power -21 g .

If it is correct mark me as brainlist

Answer 2

Answer:

c

Explanation:

1 molecule = NA moles

1 molecule = 6 × 10+23 mass / molar mass

so mass = 31( molarmass)/ 6×10+23

mass of one molecule = 5.147 × 10-23
