A. Filtration
This is because of the layers of Filter it goes through to make sure it is pure.
132 grams x (1 mol / 44 grams) = 3 moles
<span>3 moles X (22.4 L/ 1 mol) = 67.2 </span><span>L</span>
Answer:
16.566g
Explanation:
The 0.223M barium bromide means there are 0.223 moles of barium bromide is 1000ml of barium bromide solution.
Now, we firstly need to know the number of moles in 250ml
And that is = (0.223 * 250)/1000 = 0.05575 mole
Now we need to know the amount in g of barium bromide to add.
From the relation : mass = number of moles * molar mass.
The molar mass of barium bromide is 297.14g/mol
mass = 297.14 * 0.05575 = 16.566g
We are asked to solve the temperature do Potassium Nitrate KNO3 and Sodium Chloride NaCl has the same molar solubility. The answer is 44.5 degrees Celsius. As per the definition of solubility temperature, the solubility increases when the temperature increases where molecules are allowed to move faster at a higher temperature.
