Question

What is the number of atoms in 2.65g of CH 4

Answer 1

9.936x10^22 atoms of CH4

Step-by-step explanation:

grams ----> mol

2.65 g CH4 if 1 mol of CH4 = 16.04 g CH4

2.65/16.04 = 0.165 mol of CH4

mol ------> atoms

1 mol = 6.022 x 10^23 atoms

0.165 mol x 6.022x10^23 = 9.936x10^22 atoms of CH4
