Answer:

The grams in 3 mol of KBr are: 357 grams.

Step-by-step explanation:

We calculate the weight of 1 mol of KBr

Weight KBr = Weight K + Weight Br= 39,098grams +79,904grams= 119, 002 grams/mol

1 mol KBr--------------119, 002 grams

3 mol KBr-------------x= (3 mol KBr x119, 002 grams)/ 1 mol KBr= 357, 006 grams
