Respuesta :
a chemist adds of a barium chlorate solution to a reaction flask mass in grams of barium chlorate is 32grams.
Based on the given solution, the molarity of barium chlorate solution given is 0.52 M, this shows that the solution will comprise 0.52 moles in 1 L or 1000 ml of the solution. Therefore, in 200 ml, it will comprise 0.52/1000 × 200 moles of Ba(CIO3)2 = 0.52/1000 × 200 = 0.104 moles, The molecular mass of Ba(CIO3)2 is 304.23 gram per mole. So, the mass of Ba(CIO3)2 in 0.104 moles will be,= 304.23 g/mol x 0.104= 31.639 grams or 32 grams. The quantity of matter in a chemical or an item is determined by its mass. The kilogramme (kg) is the foundational SI unit of mass, although lower masses can also be expressed in millimeters (g). A balanced is what you'd use to determine mass. The moles of solute per litre of solution is quantified as molarity. For instance, when table salt dissolves in water, water exists as both the solution and the solute. Sodium chloride weights 58.44 grammes per mole. One molar solutions, or 1M, is created by dissolving 58.44 g of sodium chloride in one gallon of water. Molarity is the total of the solute's moles. litres of the solution.
