How to find molarity 1.mass 2. molar mass 3. volume of water added?

Molarity = (numer of mole solute) / (volume of the solution)

number of mole solute = mass solute/molar mass solute

Molarity =( mass solute/molar mass solute)/ (volume of the solution)=

= ( mass solute/((molar mass solute)*(volume of the solution))

If m is a mass of the solute, M is a molar mass a solute, V is a volume of the solution (we can think as a volume of water added).

Molarity = m/(M*V)

the answers would be

the first one and the second one

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
