Answer:
a. 0.026 M
Explanation:
Molarity is a measure of the molar concentration of a solution. It can be calculated by using the following formula:
Molarity = n/V
Where;
n = number of moles (mol)
V = Volume of solution (L)
Based on the information provided;
V = 23.2mL = 23.2/1000 = 0.0232 L
n = ?
To get the number of moles of KHP, we use the formula:
mole = mass/molar mass
mole (n) = 0.123/204.2
mole (n) = 0.0006024mol
Molarity = n/V
Molarity = 0.0006024 ÷ 0.0232
Molarity = 6.024 × 10^-4 ÷ 2.32 × 10^-2
Molarity = 6.024/2.32 × 10^(-4--2)
Molarity = 2.59 × 10^-2
Molarity = 0.026 M
At atmospheric pressure water boils at 100 degC.
So the water would be gas/vapor/steam.
