\text{NaOH}(aq) \longrightarrow \text{Na}^{+} (aq)+ \text{OH}^{-}(aq)\\\\k_w = [\text{H}_3 \text{O}^{+}][\text{OH}^{-}]\\\\\implies 10^{-14} = [\text{H}_3 \text{O}^{+}] \cdot 4\\\\\implies   [\text{H}_3 \text{O}^{+}]  = \dfrac{10^{-14}}4 = 2.5 \times 10^{-15}~ M\\\\\text{pH} = -\log[\text{H}_3 \text{O}^{+}] = -log(2.5 \times 10^{-15})=14.603

How to solve 5gNaCl= MolE NaCl
valentinak56 [21]

0.086mole

Explanation:

The problem is very simple. It involves conversion from mass to number of moles of NaCl

What is mole?

 A mole is a unit of measuring chemical substances. It is the amount that contains the avogadro's number of particles.

How is it related and can be converted from mass;

 

Number of moles of a substance = \frac{mass}{molar mass}

Since we know the mass, we can find the molar mass and put into this equation;

Molar mass of NaCl = 23 + 35.5 = 58.5g/mol

Number of moles of NaCl = \frac{5}{58.5}  = 0.086mole

Which mixture can be separated based on differences in the particle size of the components?
Rina8888 [55]

Answer: Mixtures you can separate are like cereal and milk. Hope that helps

Explanation:  Filteration is required to separate a mixture.

So heterogeneous mixures (that contain substances with different particle sizes)  can be separated with a filter.  

Homogeneous mixtures are uniform in composition so they will not be able to be separated.
