The atomic mass of magnesium is the weighted average of the atomic masses of
Debora [2.8K]

Answer:

2. All the naturally occurring isotopes of Mg.

Explanation:

You want to know the atomic mass of the magnesium you use in the lab. That’s “natural” magnesium. So, you must use the weighted average of all the naturally occurring isotopes in natural Mg.

1. and 3. are <em>wrong</em>. You won’t get the correct mass for natural Mg if you use only the artificial isotopes for your calculation.

4. is <em>wrong</em>. You must use all the naturally occurring isotopes. The two most abundant isotopes of Mg account for only 90 % of the atoms. If you ignore the other 10 %, your calculation will be wrong.

A solution of sodium hydroxide is standardized against potassium hydrogen phthalate (KHP, formula weight 204.2 g/mol). From the
enyata [817]

<u>Answer:</u> The molarity of NaOH solution is 0.273 M.

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Given mass of KHP = 1.794 g

Molar mass of KHP = 204.2 g/mol

Putting values in above equation, we get:

\text{Moles of KHP}=\frac{1.794g}{204.2g/mol}=0.0088mol

The chemical reaction for the reaction of KHP and NaOH follows

KHC_8H_4O_4(aq.)+NaOH\rightarrow KNaC_8H_4O_4(aq.)+H_2O(l)

By Stoichiometry of the reaction:  

1 mole of KHP reacts with 1 mole of NaOH.  

So, 0.0088 moles of KHP will react with = \frac{1}{1}\times 0.0088=0.0088mol of NaOH

To calculate the molarity of NaOH, we use the equation:

\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}

We are given:

Moles of NaOH = 0.0088 moles

Volume of solution = [32.47 - 0.23] mL = 32.24 mL = 0.03224 L      (Conversion factor:  1 L = 1000 mL)

Putting values in above equation, we get:

\text{Molarity of NaOH }=\frac{0.0088mol}{0.03224L}=0.273M

Hence, the molarity of NaOH solution is 0.273 M.
