How many grams are in 2 moles of hydrogen?
So, the mass of 2 moles of hydrogen is 4gram.
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 atoms are in 2 moles?
If we have 2 mol of Na atoms, we have 2 × (6.022 × 10 23) Na atoms, or 1.2044 × 10 24 Na atoms.
How many atoms are in 2 moles of hydrogen?
Answer: 1 water molecule = 2 Hydrogen atoms + 1 oxygen atom. So, 1 mole H2O = 1.2044×10^24 hydrogen atoms. Therefore 2 mole H2O will have 2.4088×10^24 hydrogen atoms.
How many moles is 8g of hydrogen?
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 of hydrogen does it take to react with 2 moles of oxygen to make water write out the equation?
Notice that the reaction requires 2 moles of hydrogen gas and 1 mole of oxygen gas to produce 2 moles of water.
When 8 grams 4 moles of H2 react with 2 moles of o2 how many moles of water will be formed?
We have the 4 moles of oxygen but only 4 moles of hydrogen, instead of 8. So, the 4 moles of hydrogen reacts with 2 moles of oxygen, to give 4 moles of water.
