2 litre of NH3 at 30°C and at 0.20 atmosphere is neutralized by 134 mL of a solution of H2SO4. Calculate normality of H2SO4

in what ratio 0.2M NaCl and 0.1M CaCl2 solutions are to be mixed so that in the resulting solution, the concentration of negative ions is 50% greater than the concentration of positive ions?

How much AgCl will be formed by adding 200mL of 5N HCl to a solution containing 1.7g AgNO3?

How many kg of wet NaOH containing 12% water are required to prepare 60 litre of 0.5N solution?

How much BaCl2 would be needed to make 250 mL of a solution having same concentration of Cl^- as the one containing 3.78g of NaCl per 100 mL?

A piece of Al weighing 2.7g is titrated with 75 mL of H2SO4 (sp.gr. 1.18 g/mL and 24.7% H2SO4 by mass). After the metal is completely dissolved the solution is dilute to 400mL. Calculate molarity of free H2SO4 in solution.

What would be the molarity of solution obtained by mixing equal volumes of 30% by mass H2SO4 (d=1.218 g/mL) and 70% by mass H2SO4 (d=1.610 g/mL). If the resulting solution has density 1.425 g/mL, calculate its molarity

Yes I found it. Thank you sir for your help.
