Answer:
0.022 M
Explanation:
The molarity is the number of mol solute divided by the volume of solution in liters. Since we are told there is only one acidic hydrogen in KHP the reaction is a 1 to 1 with sodium hydroxide, We then calculate the moles of sodium hydroxide required to react with the moles of KHP and proceed to calculate the molarity of the NaOH solution:
mol KHP: 0.1082 g x 1 mol/204.22 g = 0.00053 mol KHP
0.00053 mol KHP x 1 mol Naoh/1 mol KHP = 0.00053 mol NaOH
Molarity of the solution : 0.00053 mol NaOH / 0.02346 L = 0.022 M
note: The volume of sodium hydroxide needed to be converted to liters by definition of molarity.
I think u should divide the number by 2 i think.

Give me plz plz plz plz plz plz plz plz plz
<span>The activation energy was reached was 10:45 a.m. The additional energy did not affect the reaction.</span>
The answer is (4) Cu(OH)2. The valence of Cu ion is 2 positive. The valence of hydroxide(OH-) is one negative. So to balance the compound, the formula should be Cu(OH)2.
