Answer:

33.38g of NaCl are produced

0.03338kg of NaCl are produced

Explanation:

The reaction of sodium hydroxide, NaOH, and hydrogen chloride, HCl, occurs as follows:

NaOH + HCl → NaCl + H₂O

To find mass of NaCl produced we need to determine the moles of water produced. As when 1 mole of water is produced, 1 mole of NaCl is also produced we can find moles of NaCl and its mass, thus:

Moles H₂O -Molar mass: 18.015g/mol-

10.29g * (1mol / 18.015g) = 0.5712 moles H₂O = 0.5712 moles NaCl

Now, the mass of NaCl -Molar mass: 58.44g/mol- is:

0.5712 moles NaCl * (58.44g / mol) =

33.38g of NaCl are produced

0.03338kg of NaCl are produced

The mass of sodium chloride (NaCl) produced is 33.37 g (0.03337 kg). X = 33.37 g OR 0.03337 kg

From the question,

We are to determine the mass of sodium chloride produced

Let us write a balanced chemical equation for the reaction

The balanced chemical equation for the reaction is

NaOH + HCl → NaCl + H₂O

This means

1 mole of sodium hydroxide (NaOH) will react with 1 mole of hydrogen chloride(HCl) to produce 1 mole of sodium chloride (NaCl) and 1 mole of water (H₂O)

To determine the mass of sodium chloride produced

First, we will determine the number of moles of the reactants present

  • For Sodium hydroxide (NaOH)

Mass = 22.85 g

Molar mass = 40 g/mol

From the formula

[tex]Number\ of\ moles =\frac{Mass}{Molar\ mass}[/tex]

∴ Number of moles of NaOH = [tex]\frac{22.85}{40}[/tex]

Number of moles of NaOH = 0.571 moles

  • For Hydrogen chloride (HCl)

Mass = 20.82 g

Molar mass = 36.46 g/mol

Number of moles of HCl = [tex]\frac{20.82}{36.46}[/tex]

Number of moles of HCl = 0.571 moles

Now, from the balanced chemical equation,

1 mole of NaOH reacts with 1 mole of HCl to produce 1 mole of NaCl and 1 mole of H₂O

Then,

0.571 moles of NaOH will react with 0.571 moles of HCl to produce 0.571 moles of NaCl and 0.571 moles of H₂O

∴ The number of moles of sodium chloride (NaCl) produced is 0.571 moles

Now, for the mass of NaCl produced

From the formula

Mass = Number of moles × Molar mass

Number of moles of NaCl = 0.571 moles

Molar mass of NaCl = 58.44 g/mol

∴ Mass of NaCl produced = 0.571 × 58.44

Mass of NaCl produced = 33.37 g

Mass of NaCl produced = 0.03337 kg

Hence, the mass of sodium chloride (NaCl) produced is 33.37 g (0.03337 kg). X = 33.37 g OR 0.03337 kg
