Some Basic Concepts Of Chemistry Question 49

Question: How many of $0.1 N H C l$ are required to react completely with 1 g mixture of $N a_{2} C O_{3}$ and $N a H C O_{3}$ . containing equimolar amounts of two ?

Options:

A) 157.7mL

B) 15.77 mL

C) 147.7 mL

D) 14.77 mL

Show Answer

Answer:

Correct Answer: A

Solution:

[a] $\underset{x}{N a_{2} C O_{3}},$ $\underset{(1 - x)}{N a H C O_{3}},$ $\frac{x}{106} = \frac{1 - x}{84}$ given (moles are equal) $x = 0.557$ $\frac{0.557}{53} + \frac{0.443}{84} = \frac{V \times 0.1}{1000}$ $V = 157.7 m L$
