What is the mass of atoms in grams of 1.02X10 to the 24 atoms Mn?
To find the mass of 1.02×10^24 atoms of Mn, you need to calculate the atomic mass of Mn from the periodic table (54.938045 g/mol). Then, divide the number of atoms by Avogadro's number to get moles, and finally multiply by the atomic mass to get the mass in grams. The mass of 1.02×10^24 atoms of Mn would be approximately 94.64 grams.
What is the oxidation number of each atoms Mn?
The oxidation number of manganese (Mn) can vary depending on the compound it is in. In MnO2, the oxidation number of Mn is +4, while in KMnO4, the oxidation number of Mn is +7.
What is the oxidation number of Mn in 2MnO2?
In MnO2, the oxidation number of oxygen is typically -2. Since there are two oxygen atoms in MnO2, the total oxidation number contributed by oxygen is -4. The overall charge of the compound is neutral, so the oxidation number of manganese (Mn) can be calculated by setting the total oxidation number equal to zero. Therefore, the oxidation number of Mn in 2MnO2 is +4.
Oxidation number of mn in mno4-?
The oxidation number of Mn in MnO4- is +7. This is determined by balancing the charge of the whole ion (-1) with the charges of the oxygen atoms (-8) and solving for the oxidation number of Mn.
How many atoms are in 989 moles of manganese?
To find the number of atoms in 989 moles of manganese, you would use Avogadro's number, which is approximately 6.022 x 10^23 atoms per mole. Multiply this by the number of moles (989) to get the total number of atoms in 989 moles of manganese, which is approximately 5.95 x 10^26 atoms.

How many manganese atom are a liberated if 54.8 moles of Mn3O4 react with excess aluminum?
The balanced equation for the reaction is: 3Mn3O4 + 8Al -> 9Mn + 4Al2O3. This shows that 3 moles of Mn3O4 produce 9 moles of Mn. Thus, 54.8 moles of Mn3O4 would produce 9 * (54.8/3) = 164.4 moles of Mn atoms.
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! .

If the valency of Mn is 2 then how does it react with oxygen to form MnO2?
Manganese (Mn) has a valency of +2 in MnO2. It reacts with oxygen by combining one manganese atom with two oxygen atoms, forming manganese dioxide (MnO2). In this compound, each manganese atom is bonded to two oxygen atoms in a 1:2 ratio.
