The amount of grams more of potassium chlorate Jordan needs is 2.38 grams.
Since Jordan needs 15.5 grams of potassium chlorate for a science experiment and 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.
Let x represent the amount of grams more of potassium chlorate Jordan needs.
Total amount of potassium chlorate
The total amount of potassium chlorate, T = x + y + z where
- y = amount of potassium chlorate from science club = 9.72 grams and
- z = amount of potassium chlorate in science kit = 3.4 grams.
Since T = 15.5 grams,
Amount of grams more of potassium chlorate Jordan needs
Substituting the values of the variables into the equation, we have
T = x + y + z
15.5 grams = x + 9.72 grams + 3.4 grams
15.5 grams = x + 13.12 grams
So, x = 15.5 grams - 13.12 grams
x = 2.38 grams
So, the amount of grams more of potassium chlorate Jordan needs is 2.38 grams.
