If 7.3 mL of 1.25 M 𝐻𝑁𝑂_3 is required to neutralize 25.00 mL of a potassium hydroxide solution, what is the molarity of the potassium hydroxide?
𝐻𝑁𝑂_3 + KOH →KN𝑂_3 + 𝐻_2 𝑂
Mole ratio of
HNO3 ; KOH"=1:1"
"\\frac{7.3}{1000}\u00d71.25=\\frac{25}{1000}\u00d7M_k"
"M_k=\\frac{7.3\u00d71.25}{25}"
"0.365M"
