We are asked to find the mass of 0.250 mol of NaOH
molar mass of NaOH - 40 g/mol
in other words 1 mol of NaOH has a mass of 40 g
therefore 0.250 mol of NaOH has a mass of - 40 g/mol x 0.250 mol = 10.0 g
mass of 0.250 mol of NaOH is 10.0 g
Answer: option C) 5x10−6 M
Explanation:
Recall that pH + pOH = 14
9.0 + pOH = 14
pOH = 14 - 9.0
pOH = 5.0
Then, find the concentration of aqueous Ba(OH)2 that yields a pOH of 5.0
Ba(OH)2 = Ba2+ + 2OH-
Since pOH = - log(OH-)
5.0 = - 2 x log(OH-)
2 x (OH-) = Antilog (-5.0)
2 x (OH-) = 0.00001
(OH-) = 0.00001/2
(OH-) = 0.000005
Then, 0.000005 in standard form = 5x10−6 M
Answer:
Peanut oil is - a renewable resource. So I am not that sure about peanut butter
But since it is peanut oil, my best guess would be yes? It is.
