Question

battelry acid has a density 1.285 g/mL and contains 38% sulfuric acid by mass. how would you determine the mass of pure sulfuric acid

Answer 1

$m_{H_2SO_4}=\frac{V·\omega·\rho}{100}$

V - volume of battery acid, mL

p - density of battery acid, g/mL

W - mass fraction of H₂SO₄, %

Or

$m_{H_2SO_4}={V·\omega·\rho·10}$ if V(L)
