Answer:
0.508 L of solution.
Explanation:
Always a safe bet to convert to moles:
Where n is moles, m is mass, and MM is molar mass.
Now remember the equation for concentration (molarity):
Where C is the concentration, n is moles, and V is volume.
To make this easy, combine the two equations (note n appears in both, so you can do a substitution) and solve for V as the question asks:
Therefore we can make 0.508 L of solution.
Answer:
Moisture content in wet basis = 47.4 %
Explanation:
<u>Moisture content expresses the amount of water present in a moist sample.</u> <u>Dry basis and wet basis are widely used to express moisture content. </u>
The next equation express the moisture content in wet basis:
<em>where, : moisture content in wet basis and </em>
<em> : moisture content in dry basis </em>
We now calculate the moisture content in wet basis:
= 0.474 = 47.4 % wet basis
