25 cm3 of a solution sulphuric acid is required for neutralising 40 cm3 of 0.035 mol/dm3 potassium hydroxide. Find the concentration of sulphuric acid in mol/dm3

Start by writing the balanced chemical equation for this neutralization reaction ... you need to have twice as many moles of sodium hydroxide than you do of sulfuric acid. ... Plug in your values and find the number of moles of sulfuric acid - do not forget to convert the volume of the solution from cm3 to dm3.

Explanation:

google

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
