Answer:

5.3 M

Explanation:

Given data

Moles of solute: 8.0 moles

Volume of solution: 1.5 liters

The molar concentration or molarity (M) is the quotient between the moles of solute and the volume of solute expressed in liters.

M = moles of solute / volume of solution (L)

M = 8.0 mol / 1.5 L

M = 5.3 mol/ L = 5.3 M

The molarity of the solution is 5.3 M.

The ion MnOis often used to analyze for the Fe2+ content of an aqueous solution by using the (unbalanced) reaction Mno+Fe2+ + Fe

dusya [7]

Answer:

B) 0.230 M

Explanation:

The first step is to balance the reaction between the Ferrous ion and the permanganate ion:

$5~Fe^+^2~+~MnO_4^-^1~+~8H^+~->~5Fe^+^3~+~Mn^+^2~+4H_2O$

Then we have to calculate the moles of $MnO_4^-$ :

$M~=~\frac{mol}{L}$

$mol~=~M*L$

$mol~=~0.033~M*0.0633L=~0.002088~mol~MnO_4^-$

Then using the molar ratio we can find the moles of $Fe^+^2$ :

$0.002088~mol~MnO_4^-\frac{5~mol~Fe^+^2}{1~mol~MnO_4^-}=0.01044~mol~Fe^+^2$

Finally we can calculate the molarity:

$M=\frac{0.01044~mol~Fe^+^2}{0.0455~L}=0.230~M$

If an atom has an atomic number of 12 and a mass number of 16 how many protons does it have

Olenka [21]

Data:
z (atomic number)
p (protons)
e (electrons)
A (mass number)

We know that: Z = p = e

Therefore:
Z = 12
P = 12 ← protons
