Moles of Carbon dioxide produced : 2.318
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Given
70 g CO
32 g O₂
Required
moles of carbon dioxide
Solution
Reaction
2CO + O₂ ⇒ 2CO₂
mass CO₂ produced :
= mass CO + mass O₂
= 70 g + 32 g
= 102 g
mol CO₂ :
= mass : molar mass CO₂
= 102 g : 44 g/mol
= 2.318
the mass in grams of 3.5 mol of the element gold.
