Answer 2

Answer:

354.7 g/mol

Explanation:

5.137g of substance has 8.718 x 10 ^ 21 particles

the mass of substance having 6.023 x 10^23 particles is its molar mass

for getting the answer multiply 6.023 x 10^23 with 5.137g and divide the answer by 8.718 x 10^21 then we get the molar mass as 354.7 g/mol
