A sulfuric acid solution is $30%$ $H X_{2} SO X_{4}$ by mass and has density $1.22 g m L^{- 1}$ (molar mass of $H X_{2} SO X_{4}$ $= 98 g mo l^{- 1}$ ). Its normality (for complete neutralisation) is closest to:

Mass of

H X_{2} SO X_{4}

per litre

= 1220 \times 0.30 = 366 g

, so molarity

= 366/98 = 3.73 M

. With

n = 2

N = 2 \times 3.73 = 7.47 N
