Question

. Hydrogen and oxygen combine in the ratio of 1:8 by mass to form water. What mass of oxygen gas

would be required to react completely with 3 g of hydrogen gas?​

Answer 1

Explanation:

1 g of hydrogen reacts with = 8 g of oxygen

∴ 3 g of hydrogen reacts with = 8 × 3 = 24 g of oxygen

Thus, 24 g of oxygen gas would be required to react completely with 3 g of hydrogen gas.

Answer 2

Answer:

Your answer is24 g,Please make Brainliest

Explanation:

2H2​+O2​-->2H2​O

4g        32g       36g

Since, 32 g of oxygen reacts with 4g of H2​.

So, 3g of H2​ will require =3×32/4​=24 grams of O2​
