How many moles of water are produced when 5.00 moles of oxygen are used?
H2O.... In a mole of water, there is 1/2 mole of O2, right?
thank you..
yea you were right.
but i need help with alot more.
To determine how many moles of water are produced when 5.00 moles of oxygen (O2) are used, we need to know the balanced chemical equation for the reaction in which oxygen is consumed to produce water.
Assuming a balanced equation of 2 O2 --> 2 H2O, we can see that for every 2 moles of oxygen, 2 moles of water are produced. This means the molar ratio between oxygen and water is 2:2 or 1:1.
Since we have 5.00 moles of oxygen, we can determine the number of moles of water produced by using the molar ratio: 5.00 moles O2 x (1 mole H2O/1 mole O2) = 5.00 moles H2O.
Therefore, when 5.00 moles of oxygen are used, 5.00 moles of water are produced.
To determine the number of moles of water produced when a certain amount of oxygen is used, you need to use the balanced chemical equation for the reaction.
Let's assume that the reaction given is the combustion of oxygen:
2O₂(g) → 2H₂O(g)
From the balanced equation, we can see that for every 2 moles of oxygen used, 2 moles of water are produced.
So, if 2 moles of oxygen produce 2 moles of water, we can use a proportion to find out how many moles of water are produced when 5.00 moles of oxygen are used:
(2 moles O₂ / 2 moles H₂O) = (5.00 moles O₂ / X moles H₂O)
Cross-multiplying, we get:
2 moles O₂ * X moles H₂O = 2 moles H₂O * 5.00 moles O₂
Simplifying:
2X = 10
Dividing both sides by 2:
X = 5.00 moles H₂O
Therefore, when 5.00 moles of oxygen are used, 5.00 moles of water are produced.
