One litre of water was added to 500 mL of 32% HNO₃ of density 1.2g/mL.What is the % concentration of HNO₃ in the solution obtained?

How u got 350 please explain in details rates assured

When 400 g of 20% solution was

cooled ,50 g of the solute

precipitated .What is the % concentration

of the remaining solution?

The molarity and molality of a solution are M and m respectively.If the molecular weight of the solute is M',calculate the density of the solution in terms of M,m and M'

The molarity and molality of a solution are M and m respectively . if the molecular weight of the solute is M' calculate the density of the solution in terms of M ,m and M'.

Its 12.09

Is it neccesary to take the volume 1000mL?Can't we take another volume?

Please reply soon

If the density of lake water is 1.25g/mL and

contains 92 g of Na⁺ ions per kg of water ,

calculate the molality of Na⁺ ions in the

lake?

An aqueous solution of 2% non volatile solute exerts a pressure of 1.004 bar at the normal B.P of the solvent . what is the molar mass of the solute.

The vapour pressure of water is 12.3kpa at 300K . calculate vapour pressure of 1 molal solution of a non volatile solute in it

But how......

Prove that:

(1+cos pi/8) (1+cos 3pi/8)

(1+cos 5pi/8) (1+cos 7pi/8)

=1/8

Find the maximum and minimum value of

4sin²X+3cos²X+sinX/2+cosX/2.

Please give the answer of my question
