Dissolve 464.77 g KF in 1 L demineralized water.
To make a neutral 8M potassium fluoride solution, you would need to mix potassium fluoride with water in a 1:1 molar ratio. This solution would be neutral when the potassium fluoride is fully dissolved. Make sure to measure and mix the components accurately to achieve the desired concentration.
m2 - 8m + 16 = 0 (m - 4)2 = 0 so m = 4
237.5 mL (200mL if you are keeping track of significant figures). Molarity is moles/liters. To make 900mL of a 2M solution, you need 1.8 moles of solute. There are 1.8 moles of solute in 237.5 mL of 8M solution.
5m−3+8m =5m+−3+8m Combine Like Terms: =5m+−3+8m =(5m+8m)+(−3) =13m+(−3)
8m + (4n - 6m) + 9n =8m + 4n - 6m + 9n =(8m - 6m) + (4n + 9n) =2m + 13n
d=n+8m
8m-48
24am - 9an + 40bm - 15bn = 3a*(8m - 3n) + 5b*(8m - 3n) = (3a + 5b)*(8m - 3n)
1km = 1000m, so 8m = 0.008km
Isn't it the sum of all sides? 8m+8m+3m+3m = 22m
8m + 7 = -98m = -16m = -2
If: 8m = 32m+96 Then: m = -4
