There are 9.8 moles of sodium (Na) in a sample of 5.87 x 10²⁴ atoms of sodium.

HOW TO CALCULATE NUMBER OF MOLES?

The number of moles of a substance can be calculated by dividing the number of molecules in the substance by Avogadro's number. That is;

no. of moles = no. of atoms ÷ 6.02 × 10²³

According to this question, there are 5.87 x 10²⁴ atoms of sodium. The number of moles is as follows:

no. of moles = 5.87 x 10²⁴ atoms ÷ 6.02 × 10²³

no. of moles = 0.98 × 10¹

no. of moles = 9.8moles

Therefore, there are 9.8 moles of sodium (Na) in a sample of 5.87 x 10²⁴ atoms of sodium.
