21.67 grams

Step-by-step explanation:

Keiko apparently wants to have 70.97 grams of salt in the container, and has already put 49.3 grams into it. To find the quantity of additional salt that must be poured into the container, so that it will contain 70.97 grams, subtract 49.3 grams from 70.97 grams; the result is 21.67 grams.

Adding 21.67 grams of salt to the container will bring its contents up to a total of 70.97 grams.
