Answer:
103.4 moles of hydrogen
Explanation:
Given data:
Moles of C₁₂H₂₂O₁₁ = 4.70 mol
Number of moles of hydrogen present = ?
Solution:
one mole of C₁₂H₂₂O₁₁ contain 22 moles of hydrogen. Thus in order to determine total number of moles in 4.70 moles of C₁₂H₂₂O₁₁ we will multiply the 22 moles of hydrogen with 4.70 moles of C₁₂H₂₂O₁₁.
1 mole of C₁₂H₂₂O₁₁ = 22 moles of Hydrogen
4.70 × 22 moles
103.4 moles of hydrogen
