Molarity, chemistry general chemistry

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

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
