Molar and Formula Mass And Ionic Compound Name

Front

What is molar mass?

Back

Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol). It is calculated by summing the atomic masses of all atoms in a chemical formula.

How do you calculate the molar mass of a compound?

Back

To calculate the molar mass, identify the number of each type of atom in the compound, multiply by the atomic mass of each element, and sum the total.

What is the balanced equation for the reaction of chlorine gas with sodium iodide?

Back

Cl₂ + 2NaI → 2NaCl + I₂.

Front

What is an ionic compound?

Back

An ionic compound is formed when atoms transfer electrons, resulting in the formation of positively and negatively charged ions that attract each other.

Front

What is the significance of a balanced chemical equation?

Back

A balanced chemical equation ensures that the number of atoms for each element is conserved in a chemical reaction, reflecting the law of conservation of mass.

Front

What is the formula for calculating the molar mass of a compound?

Back

Molar mass = Σ (number of atoms × atomic mass of each element).
