Answer #1

HNO3+ KOH --------------------> KNO3+H2O

M1= 0.820M                                                                                         

V1= 90ml

n1=1 mole(from equation)

M2= 0.220M

V2= ?ml

n2=1 mole(from equation)

ACCORDING TO THE EQUATION

M1V1/n1= M2V2/n2

0.820*90/1= 0.220*v2/1

V2= 0.820*90/0.220= 335.45ml

335.45 ml of o.220M KOH is needed
