A pilot plant makes a liquid product in a reversible reaction.
The maximum theoretical mass of product in each trial is 60.0 g.
The plant tests two methods of separating the product from the reaction mixture.
| Separation method | Mass of product in the mixture before separation in g | Mass of product collected in g |
|---|---|---|
| A | 48.0 | 42.0 |
| B | 48.0 | 46.0 |
Calculate:
Explain the causes of the shortfall before separation and the larger mass collected using method B.
