You can put this solution on YOUR website!
HCl%2BH2O=210ml ---------> working eqn
but H2O is 120ml more than HCl ---> H2O=HCl%2B120ml
Substituting,
HCl%2BHCl%2B120=210
2HCl=210-120=90ml
cross%282%29HCl%2Fcross%282%29=cross%2890%2945ml%2Fcross%282%29
HCl=45ml
For H20=45%2B120=165ml
Simply add to check via working eqn:
45%2B165=210
210ml=210ml
Thank you,
