The balanced equation shows the reaction of sodium hydroxide with hydrochloric acid. A total of 8.72 milliliters (mL) 0.42 M reacts with 21.8 ml of of unknown concentration. The mass of HCl is 0.366 g
Hence option (B) is correct answer.
What is Balanced Chemical Equation ?
The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.
How to find the mass of solution ?
Mass = Number of moles × Molar mass
Number of moles = 0.42 × 21.8
= 0.01
Now,
Molar mass of HCl is 36.6
Number of moles is 0.01
Now put the values in above formula we get
Mass = Number of moles × Molar mass
= 0.01 × 36.6
= 0.366 g
Thus from above conclusion we can say that The balanced equation shows the reaction of sodium hydroxide with hydrochloric acid. A total of 8.72 milliliters (mL) 0.42 M reacts with 21.8 ml of of unknown concentration. The mass of HCl is 0.366 g
Hence option (B) is correct answer.
