Almost all stoichiometric problems can be solved in just four simple steps:
- Balance the equation.
- Convert units of a given substance to moles.
- Using the mole ratio, calculate the moles of substance yielded by the reaction.
- Convert moles of wanted substance to desired units.
You take 187 away from 2431
2ax + 1 = ax + 5
First, subtract 1 from both sides. / Your problem should look like: 2ax = ax + 5 - 1
Second, simplify ax + 5 - 1 to ax + 4. / Your problem should look like: 2ax = ax + 4
Third, subtract ax from both sides. / Your problem should look like: 2ax - ax = 4
Fourth, simplify 2ax - ax to ax. / Your problem should look like: ax = 4
Fifth, divide both sides by a. / Your problem should look like: x =

Answer:
x =
1,000 bows x 0.75 meters
= 750 meters
We know that Nicole is making 1,000 bows and that each bow requires 0.75 m of a piece of ribbon. Therefore, we can multiply the number of bows by the length needed to make each bow in order to determine the total meters of ribbon needed to make all the bows - it's like adding 0.75 meters a thousand times for each bow. When multiplying, you get a product of 750 meters.
