90 ml of dextrose and 4.41 litres of water.
694 mL of glucose solution 0,2 M are needed.
125 ml 500(ml) * 0.05 = 25 25 / 0.20 = 125
300 ml
150 mL x 40.0 g LiNO3/100 mL solution = 60.g of solute
My calulation says 286ml of 25% and 214ml of 60% 286 x .25= 71.50 214 x .60= 128.40 250 x .20= 50.00 250 x .60= 150.00
Image result for You prepare a less concentrated H C l solution from a stock solution with 12m concentration. If you too 100g of the stock solution to prepare 4 MHCl solution how much water is needed to prepare o find solution 9density HCL(12) = 1,89/ml? The concentration would be 0.76 mol/L.
