Question

the weight of one molecule of compound C60 h122 is

Answer 1

Molecular mass=842
One mole contains 6.022×10^23molecules
Mass of one molecule=842*10^-23/6.022=1.4*10^-21

Answer 2

Answer: 842 g

Explanation: weight of 1 atom of carbon = 12g

weight of 1 atom of hydrogen = 1g

Thus weight of 1 molecule of $C_{60}H_{122}$ which contains 60 atoms of carbon and 122 atoms of hydrogen=$60 \times 12g+122\times 1=720+122=842g$

Thus weight of 1 molecule of $C_{60}H_{122}$ is 842 g
