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

the answer

explanation:

the capillary tube was too close to the bottom of the beaker.

the ruler may have moved.

water got into the capillary tube.

the temperature was not allowed to equilibrate in the 2-4 minutes.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²
