Formulas for chem

Mass

Mass is calculated using the formula mass = mr x mole, where 'mr' is the molar mass.

Percent Yield

Percent yield is calculated by the formula % yield = actual yield/theoretical yield x 100.

Percent Economy Mass

Percent economy mass is calculated using % economy mass = mr of product/total ar of reactants x 100.

Volume of Gas

Volume of gas is determined using the formula volume of gas = 24 x moles, where 24 is the molar volume at standard conditions.

Mass Concentration Formula

Mass is calculated from concentration using the formula mass = concentration x volume.

Concentration Formula

Concentration can be determined using the formula concentration = moles / volume.

Moles From Concentration

Moles can be calculated using the formula moles = concentration x volume.

Grams per Decimeter Cubed

Concentration in g/dm³ can be found by the formula g/dm³ = answer x mr, where 'answer' typically refers to moles.
