<em>1 x 42</em>
<em>2 x 21</em>
<em>3 x 14</em>
<em>6 x 7</em>
Step-by-step explanation:
We need to find factors of 42.
Factors: <em>Two numbers when multiplied if give you the required number then those 2 numbers are factors o that number.</em>
So, Factors of 42 are:
<em>1 x 42</em>
<em>2 x 21</em>
<em>3 x 14</em>
<em>6 x 7</em>
Only these numbers when multiplied will give 42.
So, All these numbers are factors of 42

The pH of the weak acid is 3.21
Butyric acid is known as a weak acid, we need the concentration of [H+] formula of weak acid which is given by this equation :
![[H^{+}]=\sqrt{Ka . Ma}](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%5D%3D%5Csqrt%7BKa%20.%20Ma%7D)
where [H+] is the concentration of ion H+, Ka is the weak acid ionization constant, and Ma is the acid concentration.
Since we know the concentration of H+, the pH can be calculated by using
pH = -log[H+]
From question above, we know that :
Ma = 0.0250M
Ka = 1.5 x 10¯⁵
By using the equation, we can determine the concentration of [H+]
[H+] = √(Ka . Ma)
[H+] = √(1.5 x 10¯⁵ . 0.0250)
[H+] = 6.12 x 10¯⁴ M
Substituting the value of [H+] to get the pH
pH = -log[H+]
pH = -log(6.12 x 10¯⁴)
pH = 3.21
Hence, the pH of the weak acid c3h7cooh is 3.21
