Answer:
Answer: A) .346 M
Explanation:
Given:
- 450 mL
- .5 M soln
-200 mL water
1) Convert mL to L
450 mL = .45 L
200 mL = .2 L
2) Find mols in solution
.5 M = x/.45 L
x = .225 mol
3) Find total volume of solution
.45 L + .2 L =.65 L
4) Find new molarity
molarity (M) = mols solute/ L solution
y = .225 mol (from step 2)/ .65 L (from step 3)
y = .346 M
Answer: A) .346 M
Answer:

Explanation:
2) generating power by using fossil fuels is harvesting a non-renewable resource. The more you harvest = the less you have
Answer:
6) solid- dots close together
liquid- a little bit farther apart than solid
gas- far apart
7) the movement of anything from a higher area of concentration to an area of lower concentration.
8) B. evaporation
9) The solute is the thing being dissolved, the solvent is the thing dissolving it, and the solution is the product of the solute and solvent.
10) D. regular brewed coffee
*I'm not exactly sure on #10 but I hope I could've helped a little at least
Two steps by inspection 1 qt = 0.25 gallons, 13.6 g/mL = 13.6 kg/L
0.25 gallon x 3.785411784 L/gallon x 13.6 kg/L x 1 lb/0.45359237 kg = 28.374 lb.
Hope this Helps!
