A technician makes a dry solid product in a chemical process. The maximum theoretical mass of the product is 25.0 g. The technician weighs the dry product in a dish before transferring it to a storage bottle.
| Measurement | Mass in g |
|---|---|
| Empty dish | 48.35 |
| Dish and dry product before transfer | 71.55 |
| Empty storage bottle | 32.10 |
| Storage bottle and dry product after transfer | 53.85 |
The technician states, “The percentage yield is below 100% only because some product was lost during transfer.”
Calculate the percentage yield of product collected in the storage bottle.
Evaluate the technician's statement. Use data from the table.
