To solve this problem, we need to find the number of moles of
needed to completely react with 75.3 grams of
.Given the balanced chemical equation:
First, we need to calculate the molar mass of
:Molar mass of
= (2 * 1.01) + 16.00 = 34.02 g/molNext, we can calculate the number of moles of
:Number of moles of
= 75.3 g / 34.02 g/mol = 2.22 molesAccording to the balanced chemical equation, 2 moles of
react with 1 mole of
. Therefore, we can calculate the number of moles of
needed:Number of moles of
= 2.22 moles of
* (1 mole of
/ 2 moles of
) = 1.11 molesTherefore, the correct answer is 1.11 moles.
