<h3><u>Answer;</u></h3>
= 20,280.25 g or 20.28 Kg
<h3><u>Explanation;</u></h3>
Number of moles, n = Molarity × Volume
Molarity = 6.81 M
Volume = 8.7 L
Number of moles = 6.81 × 8.7
= 59.247 moles
Mass = Moles × Molar mass
= 59.247 × 34.2 g/mol
= 20,280.25 or
= 20.28 Kg
To obtain pure magnesium chloride, the following separation technique steps are employed:
- add water and filter to dissolve magnesium chloride
- evaporate the water in the filtrate and then crystallize obtain pure magnesium chloride
<h3>What are separation techniques?</h3>
Separation techniques are the techniques employed in the separation of the constituents of a mixture.
To obtain pure magnesium chloride from a mixture of magnesium chloride, magnesium, calcium carbonate, and powdered charcoal, the following steps are employed:
- add water and filter to dissolve magnesium chloride
- evaporate the water in the filtrate and then crystallize obtain pure magnesium chloride
In conclusion, separation techniques are used to separate the constituent of mixtures.
