Question

the weight of one molecule of compound c60h22 is

Answer 1

mass of C = 12
mass of H= 1
so, Molecular mass of C60H22= (60×12)+(1×22) =742

mass per molecule =molecule mass of c60h22/Avogadro's number

=742g/mol/6.023×10² mol

=123×10⁻²¹ g

Answer 2

To determine the weight of one molecule of $\mathrm{C}_{6} \mathrm{OH}_{22}$, we need to know the atomic weights of each of the elements present in this compound.

The atomic weights of each element present are:

C (Carbon) = 12

O (Oxygen) = 16

H (Hydrogen) = 1

Therefore the weight if one molecule of the given compound is

$\begin{array}{l}{=(12 \times 6)+16+(1 \times 22)} \\ {=(72+16+22)} \\ {=110}\end{array}$.

Hence, the one molecule weight of $\mathrm{C}_{6} \mathrm{OH}_{22}$ is 110.
