(c) The product sodium chloride is dissolved in water to separate it from titanium. At 30^circ C the solubility of sodium chloride is 36 kg per 100dm^3 Calculate the minimum volume of water in dm^3 at 30^circ C needed to dissolve 1989 kg sodium chloride. __ Volume of water =underline ( )dm^3

Question

Answer 1

After performing the calculation, we find that

. Therefore, the minimum volume of water needed to dissolve

of sodium chloride at

is

.

Answer 2

## Step 1:First, we need to understand the problem. The solubility of sodium chloride at

is given as

per

of water. This means that to dissolve

of sodium chloride, we need

of water. We are asked to find the minimum volume of water needed to dissolve

of sodium chloride.## Step 2:We can set up a proportion to find the volume of water needed to dissolve

of sodium chloride. The proportion is set up as follows:###

## Step 3:Next, we solve the proportion for

, which represents the volume of water needed to dissolve

of sodium chloride.###
