H, SO, from "concentrated" (18 M) sulfuric acid Dilute mL of concentrated H2SO4 to a total volume of 1.10 L with water a b. HCl from "concentrated" (12 M) reagent Dilute mL of concentrated HCI to a total volume of 110L with water c. NiCl, from the salt NiCl, 61,0 Dissolve g NiCl . 6H,O in water, and add water until the total volume of the Dissolve solution is 1.10 L d.

Answer 1

Molarity Number of moles of solute per litre of solution We know that: M1 V1 = M2V2 MMV(mL) w(8) = 1000 (mL) w(g) = amount required M = molarity M = molar mass V = volume to be prepared

As per the standard equation: M1 V1 = M2V2 (a). H2SO4 18 M xx = 0.50 M X 1100 mL 0.50 M X 1.10 L x = -= 30.55 mL 18 M (b). HCI 12 M xx = 0.50 M X 1100 mL 0.50 M X 1.10 L -= 45.83 mL 12 M X =
