Answer

Answer:

B. 0.215 mole

Explanation:

Step1: Find molar mass of $CO_2$

The molar mass of carbon (C) is approximately 12.01 g/mol and oxygen (O) is approximately 16.00 g/mol. For $CO_2$, molar mass $M = 12.01+2\times16.00=44.01$ g/mol.

Step2: Calculate number of moles

The formula for number of moles $n=\frac{m}{M}$, where $m = 9.50$ g and $M = 44.01$ g/mol. So $n=\frac{9.50}{44.01}\approx0.215$ mol.
