Jordan needs 15.5 grams of potassium chlorate for a science experiment. He was able to get 9.72 grams from his science club, and his mom found that they had 3.4 grams in their home science kit. How many more grams of potassium chlorate does Jordan need?

The number of more grams of potassium chlorate does Jordan need is 2.38 grams

Since the science club is 9.72 grams and there are 3.5 grams for home science kit

So, the total is

= 9.72+3.4

=13.12

Now

The number of more grams should be

= 15.5 - 13.12

=2.38
