Assume x is the nitric acid you had to start out.
So, x is 100% or all of the nitric acid.
19% was used in the experiment so you have 81% left and we know that is 1134 litres.
So set it up as a ratio and solve for x like so:
81% left over 100% is the same as 1134 litres left over x litres

81/100 = 1134/x

Solve for x.
