In 5.4 liters of water, the volumes of hydrogen and oxygen are in a ratio of 1: 8.

In 5.4 liters of water, the volumes of hydrogen and oxygen are in a ratio of 1: 8. How many liters of hydrogen are there in a given volume of water?

Since the volumes of hydrogen and oxygen in 5.4 liters of water are in a ratio of 1: 8, then:

contains 1x liters of hydrogen, and 8x liters of oxygen.

We get the equation:

1x + 8x = 5.4;

9x = 5.4;

x = 5.4 / 9;

x = 0.6.

Thus, a volume of 5.4 liters of water contains:

1 * 0.6 = 0.6 (liters of hydrogen);

8 * 0.6 = 4.8 (liters of oxygen).

Answer: 5.4 liters of water contains 0.6 liters of hydrogen.
