Answer:
139.5 mL.
Explanation:
To solve this question we will be making use of dilution law which is given by the equation below;
C1 × V1 = C2 × V2. Where C1 = the initial concentration, V1 = Initial volume, C2 = final concentration, V2 = Initial volume.
So, from the question we are given the following parameters; V1 = 186 mL, C1 = 0.275 M, C2 = 1.10 M and V2 = unknown (??).
Therefore, slotting in the above parameters into the dilution equation we have;
0.275 × 186= 1.10 × V2.
V2 = 0.275 × 186/ 1.10.
V2 = 46.5 mL.
The volume of solvent that has evaporated from the 0.275 M solution = 186 mL - 46.5 mL= 139.5 mL.
Answer:
6.8746142857L
Explanation:
Using ideal gas equation PV=nRT
3.50V=5.63*.0821L * atm/mol*K * (20.0C+273.15C)
23.67 g unless you're rounding to significant figures than it's 24 g
