Molarity = moles of solute/Liters of solution (40 ml = 0.04 Liters)
algebraically manipulated,
Moles of solute = Liters of solution * Molarity
Moles HCl = (0.04 Liters)(0.035 M)
= 0.0014 moles HCl

The density of 40ml of saline solution in a 50 ml beaker is 1.0046g/mL. The density will vary based upon the concentration of the salt added to the solution.
About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.

pH=12.
you would think 40ml but it is slightly less. 40 x 98% = 39.2ml when ethanol and water mix they are 98% of the volume

About 80ml of water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution.
40ml = 0.07 of a pint
A 30ml solution with a mass of 45g has a density of 45/30 or 1.5 g/ml, while a 40ml solution with a mass of 50g has a density of 50/40, or 1.25 g/ml. The 30ml solution with a mass of 45g has a higher density.
0.4
To find the dissolving rate, you divide the time by the mass. --> 200s/5grams=40mL/s
that is 0.04 litres.
