How do you find molarity
WebApr 27, 2024 · Molarity is number of moles per litre of solution and we calculate it by simply dividing moles by volume. But, if moles are not given and the w/w or w/v percentage is given then, how can we solve for the molarity? For example, if we have 2 % w/v solution of $\ce{NaOH}$, how would we find its molarity? WebAug 27, 2024 · The formula for molality is m = moles of solute / kilograms of solvent. In problem solving involving molality, we sometimes need to use additional formulas to get to the final answer. One formula we need to be aware of is the formula for density, which is d = m / v, where d is density, m is mass and v is volume. Table of Contents show.
