Calculate the number of moles of barium chloride in 427 g of a 3.82% by mass barium chloride solution? mol

How many milliliters of an 8.56% solution can be prepared from 42.8g of sucrose?

Part A The solution concentration unit of molarity (M) is related to the moles of solute and volume of solution as follows: Moles solute Molarity (M) Liters solution Solutions are sometimes prepared from a solute that is already dissolved, and one reason for the need to do so is if the solute is not stable in air. When preparing a solution of a specific concentration from a more concentrated solution, first add the volume of solution that contains the number of moles needed, and then fill to the requisite volume with solvent. Hypochlorites, which are strong oxidizers, are examples of such compounds. Sodium hypochlorite, NaOCI, is the active ingredient in many "bleach" products. Suppose you were preparing 1.0 L of a bleaching solution in a volumetric flask, and it calls for 0.24 mol of NaOCl. If all you had available was a jug of bleach that contained 0.73 M NAOCI, what volume of bleach would you need to add to the volumetric flask before you added enough water to reach the 1.0 L line?…

Please help solve these with dimensional analysis steps/ format?
