To find out how much hydrogen is in 79.2 g of pure water, we can first determine the proportion of hydrogen in water.

Since each gram of water contains 0.111 g of hydrogen, we can set up a proportion:

0.111 g of hydrogen is to 1 g of water as x g of hydrogen is to 79.2 g of water

0.111/1 = x/79.2

0.111 = x/79.2

Cross multiply:

0.111 * 79.2 = x

8.7872 = x

Therefore, there are approximately 8.79 grams of hydrogen in 79.2 grams of pure water.
