The molarity of H2SO4 is the number of moles in 1 L of solution.
The molarity is 2.0 mol/L
This means that there should be 2 moles in a 1 L solution to make up this molarity.
In this case we need to make up a 5 L solutions with that molarity. Then the amount of moles required are - 2 mol/L x 5 L = 10 mol

Probably sodium Na because it has a similar atomic mass and number
Science is constantly changing as new things are always being discovered, therefore "it is consistent and does not need to change with new discoveries" is false.
