Thailand is known for its vibrant culture and st...For a solution, C = n V (concentration = number of moles/volume). Rearranging, n = CV = 0.50× 0.25 = 0.125 mol. We need 0.125 mol of KOH and the molar mass of KOH is 56.1 g mol−1, so 56.1 ×0.125 = 7.0 g. We need 7.0 g of KOH. Answer link. 250 cm^3 = 0.25 dm^3 (= 0.25 L) For a solution, C=n/V (concentration = number of …Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol. Mole is a standard scientific unit for measuring large quantities of very small entities such as atoms and molecules. One mole contains exactly 6.022 ×10 23 particles (Avogadro's number) Steps to calculate molar massAug 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 ....
