How do you find the mass of k2co3?

How do you find the mass of k2co3?

Calculate the formula mass of potassium carbonate (K_(2)CO_(3)) (Given : Atomic masses : K = 39u , C = 12 u , O = 16 u) Thus, the formula mass of potassium carbonate is 138u.

How do you find grams in formula mass?

The actual formula for calculating the Gram Molecular Mass of a substance is : Gram Formula Mass = mass of the solute/formula mass of the solute. It is always expressed in the unit grams/mole (g/mol).

Is formula mass a gram?

Because relative atomic weight is a unitless value, relative formula mass technically does not have any units. However, grams are often used. When the relative formula mass is given in grams, then it is for 1 mole of a substance.
