Quantative chemistry

What is quantitative chemistry?

Quantitative chemistry is the branch of chemistry that focuses on measuring and quantifying chemical substances.

What is molarity?

Molarity is a measure of the concentration of a solute in a solution, defined as moles of solute per liter of solution.

What is the formula for mass percent?

Mass percent is calculated as (mass of solute / total mass of solution) x 100.

What is a mole?

A mole is a unit of measurement in chemistry that represents 6.022 x 10^23 particles of a substance.

What is the significance of the molar mass?

The molar mass is the mass of one mole of a substance, measured in grams per mole (g/mol).

How do you calculate the number of moles?

The number of moles can be calculated using the formula: moles = mass (g) / molar mass (g/mol).

What is a balanced chemical equation?

A balanced chemical equation has equal numbers of atoms for each element on both the reactant and product sides.

What is stoichiometry?

Stoichiometry is the calculation of reactants and products in chemical reactions using the relationships between quantities.

What is the ideal gas law?

The ideal gas law relates pressure, volume, temperature, and number of moles of an ideal gas: PV = nRT.

What are empirical and molecular formulas?

Empirical formulas show the simplest ratio of elements in a compound, while molecular formulas show the actual number of atoms.
