How many moles would contain 1.50 x 1024 atoms of sodium?

2.5 moles

We are given;

We are required to determine the number of moles of sodium.

Therefore;

1 mole of sodium contains 6.022 × 10^23 atoms

To get the number of moles;

 = Number of atoms ÷ Avogadro's number

 = 1.5 × 10^24 atoms ÷ 6.022 × 10^23 atoms/mol

 = 2.49 moles

= 2.5 moles

Therefore, 2.5 moles of sodium contains 1.50 × 10^24 sodium atoms
