The mass mS (g) of the solute needed to make one liter solution  of a specific molarity M (mol / liter)

M = mS / mwS

mwS: molecular weight of solute

mS = M * mwS

Since the mass of the solute contained in the solution m (g) of P (%) must be mS (g),

mS = m * P / 100 = M * mwS

m = M * mwS * 100 / P

If the density of the solution is d (g / ml), then the volume V (ml) of the solution is

V = m / d = (M * mwS * 100 / P) / d

Therefore, when 1 liter of P (%) solution V (ml) is filled with water, it becomes a specific molarity solution.
