To find out how many grams of NH4Cl will dissolve in 20 g of water, we need to use the given solubility information.
Given:
Solubility of NH4Cl = 50 g/100 g water
Step 1: Convert the given solubility to a ratio.
The given solubility is 50 g NH4Cl per 100 g water. We need to convert this to a ratio of NH4Cl to water. To do this, we divide both parts of the ratio by 100:
50 g NH4Cl / 100 g water = 0.5 g NH4Cl / 1 g water
Now we have the ratio of NH4Cl to water as 0.5 g NH4Cl to 1 g water.
Step 2: Use the ratio to find the amount of NH4Cl that will dissolve in 20 g of water.
Since we have the ratio of NH4Cl to water, we can set up a proportion to find the amount of NH4Cl that will dissolve in 20 g of water.
0.5 g NH4Cl / 1 g water = x g NH4Cl / 20 g water
Cross-multiplying, we get:
0.5 g NH4Cl * 20 g water = 1 g water * x g NH4Cl
10 g NH4Cl = x g NH4Cl
Therefore, 10 grams of NH4Cl will dissolve in 20 g of water.
