The number of moles in 1.23 x 10⁵⁰ molecules of hydrogen is 0.204 × 10²⁷moles
HOW TO CALCULATE NUMBER OF MOLES:
The number of moles in a molecule of a substance can be calculated by dividing the number of molecules by Avogadro's number. That is;
no. of moles = no. of molecules ÷ 6.02 × 10²³
- According to this question, there are 1.23 x 10⁵⁰ molecules of hydrogen. The number of moles in this is calculated as follows:
no. of moles = 1.23 x 10⁵⁰ ÷ 6.02 × 10²³
no. of moles = 0.204 × 10²⁷moles
Therefore, there are 0.204 × 10²⁷ moles in 1.23 x 10⁵⁰ molecules of hydrogen.
