Answer:
Step-by-step explanation:
We must use stoichiometry to solve this, which is the calculation of reactants and products in a reaction using ratios.
Let's analyze the reaction given.
Now, look at the coefficients, or numbers in front of the molecule formulas. If there isn't a coefficient, then a 1 is implied.
We want to find how many moles of potassium chloride (KCl) are produced from 4.8 moles of magnesium chloride (MgCl₂). Check the coefficients for these molecules.
- MgCl₂: no coefficient= coefficient of 1
- KCl: coefficient of 2
The coefficient represents the number of moles. Therefore, 1 mole of magnesium chloride produces 2 moles of potassium chloride. We can set up a ratio using this information.
Multiply by the given number of moles of magnesium chloride: 4.8
Flip the ratio so the moles of magnesium chloride cancel out.
9.6 moles of potassium chloride are produced from 4.8 moles of magnesium chloride.
