Question #84631
1 Answer
Explanation:
Since sodium hydroxide is a strong base and hydrochloric acid is a strong acid, they both completely dissociate when dissolved in water.
In a strong acid-strong base reaction, the moles of hydrogen ions must equal the moles of hydroxide ions in order to create a neutral solution.
#"HCl" + "NaOH" -> "NaCl" + "H"_2"O"#
Divide the
#"73 g"/"36.46 g/mol" = "2.002 moles"#
Then, using the fact that the moles of hydrochloric acid equal the moles of sodium hydroxide, we know that there are
We would multiply that
#"2.002 moles" * "39.997 g/mol" = "80. g NaOH"#
