Find the number of moles of water that can be formed if you have 138 mol of hydrogen gas and 64 mol of oxygen gas.
charle [14.2K]
2H₂₍g₎ + O₂ ₍g₎→ 2H₂O

138 mol H₂ × (2 mol H₂O ÷ 2 mol H₂)= 138 mol H₂O
64 mol O₂ × (2 mol H₂O ÷ 1 mol O₂)= 128 mol H₂O

128 mol H₂O

A fixed amount of oxygen gas is held in a .500 L tank at a pressure of 4.39 atm. The tank is connected to an empty 1.50 L tank b
DochEvi [55]

Answer:

1.0975 atm.

Explanation:

<em>According to Boyle’s Law:</em> " At constant temperature , the  volume of a given quantity of a gas  varies inversely with its pressure".

P α 1/V.

<em>∴ P₁V₁ = P₂V₂.</em>

P₁ = 4.39 atm, V₁ = 0.5 L.

P₂ = ??? atm, V₂ = 2.0 L.

<em>∴ P₂ = P₁V₁/V₂</em> = (4.39 atm)(0.5 L) / (2.0 L) = <em>1.0975 atm.</em>
