I need help. please show step by step?
How many milliliters of 1.0 M NaOH would be required to completely neutralize 40.0 mL of 0.60 M
mols HCl - M x L = ?
Equn is HCl + NaOH ==>NaOH + H2O so the ratio is 1 mol HCl to 1 mol NaOH. That means mols NaOH = mols HCl and you have that from above.
Then M NaOH = mols NaOH/L NaOH. you have M and mols, solve for L and convert to mL.
