One soluble 18.0% ammonium sulfate has a density of 1.10 g / mL. a) How many grams (NH4)2SO4 are needed to prepare 275 mL of this solution? b)How much mL of this solution are found im 90.0 g of ammonium sulfate?
1 Answer
So you gots
Explanation:
We work out (i), the concentration of this solution in
...we take a
And (ii), we work out the mass of solute required for the specified VOLUME....
We know that
And thus
And (iii), this represents a mass of
And (iv), if we got a volume of this solution THAT contains
And to get the required volume we take the quotient...
And you can check the arithmetic. All care taken, but no responsibility admitted....
