How many grams of Mn are in 4.0 moles of the element?
4,0 moles of the manganese contain 219,75 g.
How many moles of manganese are contained in 0 point 1 moles of hydrated manganese II sulphate MnSO4 4H2O which has an RFM of 223?
I must have the same sheet as you as I have the exact same question. Okay, The RFM of Manganese (Mn) is 54.9 The RFM of MnSO4 4H20 is 223 The percentage of Mn in MnSO4 4H2O is 54.9/223 X 100 and that is 24.6 % 0.1 Moles of MnSO4 4H20 is 223/100 X10 = 22.3 24.6 % (percentage of Mn in MnSO4 4H2O) of 22.3 (0.1 Moles of MnSO4 4H2O) is 5.49g Then you do 5.49g/54.9g (RFM of Mn) which is 0.1 Moles of Mn, which is your answer.
Why the colour of KMnO4 is purple even though Mn exhibit plus 7 oxidation state?
its MnO4 that gives purple colour to the KMnO4 solution. MnO4 absorbs all the six colours present in the white light except for indigo and this colour reflects back to our eyes that is why we see it as purple coloured solution.

What is the oxidation number for MnO4-2?
manganese is a metal element. It shows +4 in Mno4 ompouund.
What is the symbol for cupric sulfate?
Permanganate is a poly atomic ion, not an element. It contains two elements: manganese (Mn) and oxygen (O). The formula of the permanganate ion is MnO4-
How can write formula of manganese II superoxide?
Molecular: Mn(O2)2empirical: MnO4
What are the oxidation numbers of the atoms in the MnO4- ion?
+7 for Mn -2 for each O
What is the oxidation number of MnO4?
O.S. of Mn = +7 O.S. of O = -2 O.N. of cpd = -1
How are the oxygen atoms balanced for the red-ox equations in acidic solutions?
To balance the oxygens, you add H2O to one side, and the H^+ to the other (acid). Example:MnO4^- ===> Mn^2+ add 4 H2O to the right side MnO4^- ===> Mn^2+ + 4H2O this balances the oxygens. Now add 8H^+ to the left side MnO4^- + 8H^+ ===> Mn^2+ + 4H2O Now this is balanced for Mn, H and O. You now only have to balance the electrons (charge).
How many moles of Mn atoms are there in 16.1201 grams of KMnO4?
First start with what you know to find the total moles. Mn = 54.94g O = 16g 54.94g * 2 = 109.88g 16 * 3 = 48g Add these to get the weight of Mn2O3 which = 157.88 Divide 157.88 / 286 to get your total moles present, which = .552 Mols To find moles Mn, divide 54.94 by the total weight which is 157.88. This gives you your moles Mn, which is .348 mols. Since you have Mn2, multiply that number by 2 to get .695 mols Now you can divide Mol(Mn) by your total moles (.552) to get your moles Mn So .695 mol Mn2O3 / .552 mol Mn = 1.1 Mol Mn since 1.1 * 54.94 = 60 pct of the Molar Mass, this number makes sense since there is more Mn than O, the proportion seems correct. hope this helped! .
What colour change occurs when h2o2 is added to kmno4?
MnO4- turns into Mn+2.So purple change into pale pink.
What is the oxidation numbers of manganese in MnO4 1-?
The oxidation number of manganese in KMnO4 is 7+.
What is the oxidation number in MnO4?
K has an oxidation number of +1 O has an oxidation number of (-2) x 4 So... the oxidation number for Mn is whatever is needed to make 1-8 equal to zero. Therefore, the oxidation number for Mn is +7
