Number of moles of BaCO3 = 6.85 g / 197.34 g/mol = 0.0347 mole
From the balanced equation we can say that
1 mole of BaCO3 requires 2 mole of HNO3 so
0.0347 mole of BaCO3 will require
= 0.0347 mole of BaCO3 *(2 mole of HNO3 / 1 mole of BaCO3)
= 0.0694 mole of HNO3
molarity of HNO3 = number of moles of HNO3 / volume of solution in L
0.577 = 0.0694 / volume of solution in L
volume of solution in L = 0.0694 / 0.577 = 0.120 L
1 L = 1000 mL
0.120 L = 120 mL
Therefore, the volume of HNO3 required would be 120 mL
