pure water is made up of oxygen and hydrogen each gram of water contains 0.111 g of hydrogen about how much hydrogen is in 79.2 g of pure water?

Answer 1

To find out how much hydrogen is in 79.2 g of water, we need to determine the percentage of hydrogen in water first.

Since each gram of water contains 0.111 g of hydrogen, we can calculate the percentage of hydrogen in water as follows:

(0.111 g H / 1 g H2O) * 100 = 11.1%

Now, we can calculate how much hydrogen is in 79.2 g of water using the calculated percentage:

79.2 g H2O * 11.1% = 8.8 g H

There is approximately 8.8 g of hydrogen in 79.2 g of pure water.
