Question

The approximate production of sodium carbonate per month is $424\times {10}^{6}g$ while that of methyl alcohol is $320\times {10}^{6}g$. Which of the following is produced more in terms of number of moles?

• A. Sodium carbonate
• B. Methyl alcohol
• C. Both (A) and (B)
• D. Data insufficient

Answer 1

Answer: (B)

Methyl alcohol

Molar weight of ${Na}_{2}C{O}_3=2\times 23+12+3\times 16=106$

Thus $\frac{424\times {10}^6}{106}=4\times {10}^6$ moles of ${Na}_{2}C{O}_3$ produced

Also molar weight of $C{H}_{3}OH=12+3\times 1+16+1=32$

Thus $\frac{320\times {10}^6}{32}={10}^5$ moles of $C{H}_{3}OH$ produced. Hence clearly $C{H}_{3}OH$ is produced more in terms of moles.
