You can use the formula M1 x V1 = M2 x V2 where M1 is the molarity of the first substance and V1 is the volume of the substance. M2 is the molarity of the 2nd substance and V2 is the volume of the substance
if substance 1 is HCl and 2 is KOH we can set up the following equation
x moles / liter (unknown) x .02 liters = .5 moles/ liter x .032 liters
x moles / liter x .02 liters = .016 moles
x moles / liter = .016/.02 liters
x moles / liter = .8 moles/ liter
You have . 8M HCL
They can still be effected it large quantities of soap are added to water
because more soap eliminates the effect the minerals in hard water has on
its cleaning capacity.
Hard water contains minerals such as
They reduce the cleaning capacity of the soap. This is why soft water is
preferably used as it doesn't contain these minerals.
When more soap is added, the effect of the minerals reduces thereby
bringing about very little or no effect on the cleaning capacity of the soap.

Answer:
The new findings support the theory that walking first arose underwater, preceding the move onto land and the development of toes and limbs adapted to land perambulation.
The mass of the solid product of the reaction is determined by weighing.
