How many milliliters of a 4.0-molar solution
of HCl are needed to completely neutralize
60 milliliters of a 3.2-molar solution of NaOH?

HCl + NaOH → NaCl + H2O

No. of moles of NaOH = MV/1000

= 3.2X60/1000

= 0.192 mol

**M is your concentration of solution, V is the volume of solution either in cm³ or mL cuz they are equal**

1 mol of NaOH reacted with 1 mol of HCl. No. of moles of HCl needed to react with 0.192mol of NaOH

= 0.192x1/1

= 0.192mol

Volume of HCl = no. of moles x 1000 / M

= 0.192 x 1000 / 4.0

= 48mL

explanation:

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
