We draw up a chemical equation, not forgetting to put down the coefficients: 2NaOH + H2SO4 = Na2SO4 + 2H2O.
Find the mass of H2SO4: m (H2SO4) = 8 * 98/80 = 9.8g.
It is known that 9g is 10%. Then we denote 100% by Xr.
Find X: X = 9.8 * 100/10 = 98g.
We find the volume of the solution: V (solution) = m / p = 98 / 1.1 = 89ml.
Answer: V (sol) = 89ml.
