Discuss how do you determine the grams needed and determine the numbers of grams (to the nearest 0.01 g) of NH4Cl (Mm = 53.49 g/mol) must be added to the 650. mL of 0.898-M solution of NH3 in order to prepare a pH = 10.50 buffer?

Product A gives $6.00 per unit to profit, product B gives $4.00 per unit, and product C gives $10.00 per unit. Determine optimum mix of products in terms of maximizing contributions to profits?
Consider the titration among the 25.00 ml of 1.00 x10-2 M solution of hydroxyl acetic acid with 1.50 x10-2 M solution of KOH. Determine the pH for 0.00ml and 2.00ml of base added. Ka= 1.48 x10-4.
Explain how much KOH(s) must be dissolved in exactly 1 L of solution, so that 25.00mL of this solution is needed to titrate to the equivalence point a solution which is having 0.3220g of a monoprotic acid with a molar mass of 204.6g/mol?
Assuming the specific heat of the resulting solution is equal to that of pure water; determine the final temperature of the solution if the molar heat of solution of a substance is found to be +31.5 kJ/mol.
Explain how much heat is released when the 4.25 g of propanol is burned? Determine the numbers of grams of propanol must be burned to obtain the 150. kJ of heat ?
