$5 ml$ of $8 N$ $\ce{HNO3}$ , $4.8 ml$ of $5 N$ $\ce{HCl}$ and a certain volume of $17 M$ $\ce{H2SO4}$ are mixed together and made up to $2 L$ . $30 ml$ of this acid is solution neutralizes exactly $42.9 ml$ of sodium carbonate solution containing $1g$ of $\ce{Na2CO3}.10\ce{H2O}$ in $100 ml$ water.Calculate the mass of $\ce{SO4}$ units in solution in $GRAMS$ up to 3 decimal places.
