How many moles are present in 5.00 grams of CO₂?

Question

Quizplus · Accepted Answer

To determine the number of moles present in 5.00 grams of CO₂, we need to use the formula: moles = mass/molar mass 1. Calculate the molar mass of CO₂: C (1x12.01) + O (1x16.00) + S (1x32.06) + 2U1B (2x10.81) = 76.70 g/mol 2. Plug in the values: moles = 5.00 g / 76.70 g/mol = 0.065 moles or 0.114 moles (rounded to three significant figures) Therefore, the best choice is B, 0.114 moles of CO₂.
