Question

question 11 (1 point)
if 24 g of c is consumed in 2c + o₂ → 2co, the mass of carbon monoxide produced is
32 g
28 g
56 g
112 g

Explanation:

Step1: Calculate moles of C

Molar mass of \( C = 12\space g/mol\).
Moles of \( C=\frac{24\space g}{12\space g/mol}=2\space mol\)

Step2: Use mole ratio

From \( 2C + O_2
ightarrow2CO\), mole ratio \( C:CO = 2:2 = 1:1\).
So moles of \( CO = 2\space mol\)

Step3: Calculate mass of CO

Molar mass of \( CO=(12 + 16)\space g/mol = 28\space g/mol\)
Mass of \( CO=2\space mol\times28\space g/mol = 56\space g\)

Answer:

C. \( 56\space g\)
