Question

Suppose element y has a molar mass 52.01 g/mole. How many atoms of element Y are 52.01 g of element Y?

Answer 1

There are 6.022 × 1023 atoms of element Y in 52.01 g of element Y since this amount corresponds to 1 mole and 1 mole contains Avogadro's number of atoms.

Step-by-step explanation:

If element Y has a molar mass of 52.01 g/mole, to find out how many atoms of element Y are in 52.01 g of element Y, we need to use Avogadro's number. 1 mole of any substance contains 6.022 × 1023 atoms of that substance. Therefore, since 52.01 g of element Y is equal to 1 mole, it will contain 6.022 × 1023 atoms of element Y.
