Chapter 9: Q. 9.91 (page 317)

If $N a C l$ has a solubility of $36.0 g i n 100 g$ of $H_{2} O a t 100 ° C$ . how many grams of water are needed to prepare a saturated solution containing $80.0 g$ of $N a C l$ ? $(9.3)$

Short Answer

Expert verified

As the concluded, make a saturated solution with $80.0 g N a C l a t 20 ° C, 222 g$ water is needed.

Step by step solution

Introduction.

A solvent is one in which there is far too much solute that adding more would cause it to dissolve.

Given data.

$36.0 g$ of solid $N a C l$ is decomposed in $100 g$ of water to make a supersaturation of $N a C l a t 20 ° C$ .

In $(100 / 36) g$ of water, $1 g$ of solid $N a C l$ is digested.

Explanation.

Estimate how much water is required to make $80.0 g o f N a C l .$

$= \frac{100 g}{36 g} \times 80 g$

$= 222 g$

To make a saturated solution holding $80.0 g N a C l$ at $20 ° C, 222 g$ water is required.
