Answer:
- <em>The molarity of the solution is </em><u>1.0 M</u>
Explanation:
<u>1) Data:</u>
a) n = 0.50 mol
b) V = 500 ml
c) M = ?
<u>2) Formula:</u>
- Molarity, M = number of moles of solute / volume of solution in liters
M = n / V (liter)
<u>3) Conversion of units:</u>
- 500 ml × 1.00 liter / 1,000 ml = 0.500 liter
<u>4) Solution:</u>
Substitute in the formula:
- M = n / V (liter) = 0.50 mol / 0.500 liter = 1.0 mol / liter = 1.0 M
The answer must be reported with two significant figures.
Complete one rotation.
Hope this helps.

Answer:
Explanation:
Upon arrival we needed to hunt in this new land we only had five refills and they needed 50 g of gunpowder to be shot once. We only have 15 pounds of gunpowder. It is taking six shots to kill one of these wild turkeys. How many turkeys can be shot with 15 pounds of gunpowder?
If we had plenty of refills, and it takes 6 shots to kill a wild turkey at 50 gms of gunpowder per shot, then each turkey requires 6X50 =300gms of gunpowder. We have 15X454 gms of gunpowder and have the potential to kill 15X454/300=22.7 or 22 turkeys.and it takes 6 shots to kill a wild turkey.
The limiting reagent is the number of refills, and withonly 5, we are out of luck and can't kill one turkey
