Molarity= (number of moles of that substance) / (Volume of solution in litres)

7= (number of moles of HCl) / 0.05

Thus,

Number of moles of HCl = 7 x 0.05 = 0.35

The number of moles of HCl will remain unchanged.

Now, for new solution,

0.35= 0.35 / (New volume of solution in litres)

Thus,

New volume = 1 litre

Thus, amount of water added = 1- 0.05 litre = 5.0 M

Why is the pressure 101.3kPa significant
nydimaria [60]

Answer:

Explanation:

The kPa-kilopascal is the unit of pressure. It was named after Blaise Pascal, a mathematician and physicist.

The kPa is 1000Pa. Kilo stands for 1000. Now what is a pascal?

A pascal is the amount of force(Newton) exerted per unit area.

            1Pa = 1Nm⁻²

At the standard atmospheric level, the pressure is 101.325 x 10³ Nm⁻² i.e the atmosphere exerts a pressure of 101.325 x 10³N in an area of a body.

This unit is used to calculate pressure. It can be converted to other units.
