Question

how many grams in 5 moles of co₂? (nearest whole number; no units)

Explanation:

Step1: Calculate molar mass of \( CO_2 \)

Molar mass of \( C \) is \( 12.01 \, g/mol \), molar mass of \( O \) is \( 16.00 \, g/mol \). For \( CO_2 \), molar mass \( M = 12.01 + 2\times16.00 = 44.01 \, g/mol \).

Step2: Use moles to grams formula (\( m = n\times M \))

Given \( n = 5 \, moles \), \( M = 44.01 \, g/mol \). So \( m = 5\times44.01 = 220.05 \), rounded to nearest whole number.

Answer:

220
