Question

Hydrogen and oxygen combine in the ratio of 1:8 mass to form water what mass of oxygen gas would be required to react completely with 3 g of hydrogen gas

Answer 1

Answer:

24g of Oxygen

Explanation:

If 8g of oxygen is taken for for 1g of hydrogen then, to react 3g of hydrogen with oxygen we required 8×3= 24g of oxygen

Answer 2

Given - Ratio of hydrogen and oxygen

Find - Required mass of oxygen

Solution - 3 grams of hydrogen will react with 24 grams of oxygen.

As per the given information, 1 gram of hydrogen reacts with 8 grams of oxygen.

So, 3 grams of hydrogen will react with the amount of oxygen = 8*3/1

Performing multiplication to find the required amount of oxygen.

Amount of oxygen = 24 gram

Thus, 3 grams of hydrogen will react with 24 grams of oxygen.
