Answer:
17.25 L
Explanation:
I converted 100g into moles and converted the amount of moles into L.
Hey there!
N₂ has a density of 1.25 grams per liter.
We have 2.31 liters of N₂.
2.31 x 1.25 = 2.8875
We have 2.8875 grams of N₂.
Find molar mass of N₂:
N: 2 x 14
------------
28 g/mol
2.8875 ÷ 28 = 0.10
There is 0.10 mol of nitrogen in 2.31 L of N₂.
Hope this helps!

Answer:
Answer: 760 uM
Explanation:
the addition of solvent to a solution in a such away that the volume of the solution increases and the concentration decreases is a process know as dilution
The concentration and the volume of the dilute and concentrated solution are given below as follows

Concentrated solution Dilute solution
Given that M1 = 97.0uM
V1 = 47.0 mL
V2 = 6.0 mL
M2 = ?
Therefore M1V1 = M2V2
M2 = M1V1/V2
M2 = (97*47)/6
M2 = 760 uM
Answer: 760 uM
