How many moles are present in 8gm of oxygen?

How many moles are in 8gm of oxygen?

The molar mass of oxygen is 16. Conclusion: 8 g of oxygen is composed of 0.5 moles.

How many moles is in oxygen?

One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.

How many moles are there in 8gm of the hydrogen gas?

Answer Expert Verified

= 3.01 x 10²³ moles. Therefore, 8 g of H₂ will have = 8 x 3.01 x 10²³ moles = 24.08 x 10²³ moles. Thus, 8 g of H₂ will have 24.08 x 10²³ moles of hydrogen molecules.

How many moles are in 8.0 g of O2?

Moles = 8/32 = 1/4 moles.

How many moles are in 32g of oxygen?

And we know that When the given mass is divided by the molar mass of the gas. We will get the number of moles present in that gas so here it is =1. we get the answer as 1. So the number of moles present in 32 gram of oxygen is 1.

How many moles of oxygen react with 2 moles of hydrogen?

And we introduced balancing reactions in terms of keeping the number of atoms the same on each side of the reaction equation. While this is not completely incorrect it is not the way a chemist would state the equation. A chemist would say that 2 moles of hydrogen react with 1 mole of oxygen to form 2 moles of water.

How many molecule of oxygen are present in 8g of oxygen gas?

1 g contains → 6.022 × 1023 / 32 molecules of di oxygen. ⇒ 1 g contains → 0.188 × 1023 molecules of di oxygen. ∴ 8 g contains → 0.188 × 8 × 1023 molecules of di oxygen.
