Question

How many grams of Mg are there in a sample of Mg that contains 6.61×1023 atoms?

Answer 1

The answer to your question is: 26.7 g of Mg

Step-by-step explanation:

Data

Mg = ? g

Mg = 6.61 x 10²³ atoms

Atomic mass Mg = 24.3 g

Rule of three

24.3 g of Mg ----------------- 6.023 x 10²³ atoms

x ---------------- 6.61 x 10²³ atoms

x = (6.61 x 10²³ x 24.3) / 6.023 x 10²³

x = 26.7 g of Mg
