Solution Stoichiometry

Front

What is solution stoichiometry?

Back

Solution stoichiometry is the calculation of the quantities of reactants and products in chemical reactions that occur in solution, using molarity and volume.

Front

Define molarity (M).

Back

Molarity is a measure of concentration, defined as the number of moles of solute per liter of solution (mol/L).

Front

How do you calculate moles from molarity and volume?

Back

Moles = Molarity (M) × Volume (L).

What is the balanced equation for the reaction between HCl and KOH?

Back

HCl + KOH → H2O + KCl.

Front

What is the stoichiometric ratio in the reaction between HCl and KOH?

Back

The stoichiometric ratio is 1:1.

Front

How do you determine the molarity of an acid from a neutralization reaction?

Back

Use the formula: Molarity of acid = (Molarity of base × Volume of base) / Volume of acid.

Front

What is the molar mass of AgBr?

Back

The molar mass of AgBr is approximately 187.77 g/mol.

Front

How do you calculate the mass of a product formed in a reaction?

Back

Mass = Moles × Molar Mass.

Front

What is the balanced equation for the reaction of H3PO4 with Zn?

Back

2 H3PO4 + 3 Zn → Zn3(PO4)2 + 3 H2.

Front

How do you find the volume of a solution needed for a reaction?

Back

Volume = Moles / Molarity.
