Calculate the mass of sodium sulphate required to prepare its 20

In the given question, mass% of sodium sulphate solution = 20 % Mass of the solvent =100 g Let the mass of solute (sodium sulphate) = xg Applying the formula, mass % = mass of solute mass of solution × 100 = mass of solute × 100 mass of solute + mass of solvent 20 = x g ( x + 100 ) g × 100 ⇒ 20 ( x + 100 ) = 100 x 20 x + 2000 = 100 ξ m p l i e s 100 x − 20 x = 2000 80 x = 2000 ⇒ x = 2000 80 = 25 g Mass of sodium sulphate = 25 g hello everyone this question calculate the mass of sodium sulphate sodium sulphate which is required to prepare its 20% 20 mass percent solution in hundred gram of water right so what we need to find out in this question the mass of sodium sulphate white ok so first of all there is given here given here the mass percent write the mass percent that is 20% right and it also gives the mass of solvent rate mass of solvent that is hundred gram solvent but it is here solvent is water weight solvent is water which 100 gram right and the mass of solute white mass of solute what is solute here that is sodium sulphate sodium sulphate so we need to find out the mass of the solute sodium sulphate ok to let so this week and let mass of solute of sodium sulphate is x g b ok in order to find out the mass of sodium sulphate what we need to find out first to find out mass of solution write mass of solution which is the formula for the mass of solution is mass of solute mass of solute mass of solvent rate mass of solvent and solute is extreme right Mercedes x cream a...
