What is the minimum mass of sodium hydroxide required to neutralize a solution that was prepared by dissolving 9.16 g of hydrochloric acid (hcl) in excess water?

10.04 g of NaOH is required for neutralization

Explanation:

neutralization reaction:

Molar mass of NaOH = 40 g/mol

Molar mass of HCl = 36.5 g/mol

So, 9.16 g of HCl = moles of HCl = 0.251 moles of HCl

According to neutralization reaction, 1 mol of NaOH is required to neutralize 1 mol of HCl

So, 0.251 moles of NaOH are required to neutralize 0.251 moles of HCl

So mass of NaOH required for neutralization = () g = 10.04 g

wher is the rest of the question

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
