To calculate the number of grams of H2O produced, we need to consider the balanced chemical equation.
From the chemical equation:
2H2 + O2 -> 2H2O
We can see that 2 moles of H2 produce 2 moles of H2O.
Given that 4.00 moles of H2 is reacted, we can use this information to calculate the moles of H2O produced.
4.00 moles H2 * (2 moles H2O / 2 moles H2) = 4.00 moles H2O
To convert moles of H2O to grams of H2O, we need to use the molar mass of H2O, which is 18.015 g/mol.
4.00 moles H2O * 18.015 g/mol = 72.06 grams
Therefore, the number of grams of H2O that form is 72.06 grams, with 4 significant figures.
Calculate the number of grams of the product H2O that form. Be sure your answer has the correct number of significant figures.
