Explanation:
As we have the equation balanced, we need to know, form the percent yield and the theoretical yield, the actual yield:
With this, we need to convert the mass of sucrose into moles:
Now, with the yield, we apply the rule of three, with the actual yield, to know the moles of citric acid produced:
Therefore, 5392.93 moles of citric acid are produced, now we need to know the mass:
Explanation:
In sugar solution 200 g has sugar 10 g
In sugar solution 100 g has sugar 10/200 × 100
= 5 %w/w
The answers that apply are;
- gas molecules are closer together
- air weighs more
- air is hotter
When air is compressed, it means the same volume of space is occupied by more air molecules. This, therefore, means that the molecules are hitting each other with a higher frequency hence become hotter with more compression. It weighs more because there are more molecules in the same volume of space.
