Computing molar mass step by step. First, compute the number of each atom in KO 1 H: K: 1, O: 1, 1 H: 1. Then, lookup atomic weights for each element in periodic table: K: 39.0983, O: 15.9994, 1 H: 1.00782503207. Now, compute the sum of products of number of atoms to the atomic weight: Molar mass (KO 1 H) = ∑ Count i * Weight i =. Aug 23, 2022 ... The molarity of the solution containing 2.8 % mass-volume solution of KOH /( Given atomic mass of K=39) is : (A) 0.1 M (B) 0.5 M (C) 0.2 M ...Molar mass of KOH, Potassium Hydroxide is 56.10564 g/mol. 39,0983+15,9994+1,00794. Mass percentage of the elements in the composition. Element Symbol ... The molar mass is a physical property, which is defined as the mass of a substance divided by its amount of substance in moles. In other words, it is the mass of one mole of a particular ...Molar mass μ is a physical quantity that tells us what the mass of one mole of a substance is. We can calculate it in a simple way by dividing the mass of the ….
