Explanation:
The pH of the solution is 9.63 ± 0.03.
we know that
pH= -log[H+]
⇒[H+] =
= =
Now to find absolute error we use the formula
Absolute error/[H+] =ln10(uncertainity)
Absolute error = ln10×[H+] ×0.03
=

Answer:
218.98 grams
Explanation:
Given that,
No. of moles, n = 2.3
The molar mass of magnesium chloride is 95.211 g/mol.
We need to find the mass of 2.3 moles of magnesium chloride.
We know that,
No. of moles = given mass/molar mass
Let m be the given mass. So,
So, the required mass is equal to 218.98 grams.
