The formula for chromium(III) sulfate is Cr2(SO4)3. The subscript after the parentheses in this formula means that all the atoms inside it occur as many times as the subscript. Therefore, the total number of atoms in this formula is 2 + 3(1 + 4) = 2 + (3 X 5) = 17.

∙ 12y agoChromium and other metals with metallic bonding do not literally have "moles" but rather "formula units" with similar properties. The formula unit is a single atom; therefore, the number of atoms in 3 formula units is 3 times Avogadro's Number or about 1.81 X 1024 atoms.

What is the oxidation number of Fe and Cr in FeCr2O7?
The possible oxidation numbers for iron cations are +2 and +3. Oxygen in oxyanions is usually assigned an oxidation number of -2, producing a total negative charge of -14 for the seven oxygen atoms in a dichromate anion. If the iron cation has an oxidation number of +2, the two chromium atoms must have a total oxidation number of +12, which is possible when each chromium atom has an oxidation number of +6. An iron (III) cation would require the chromium atoms to have a non integral charge, which is not possible since electrons with half charges are not known. Therefore, the oxidation number of iron in the compound is +2 and the oxidation number for chromium is +6.
How many atoms are represented in one unit of sodium sulfate?
The formula for sodium sulfate is Na2SO4. Therefore, there are 2 sodium atoms, one sulfur atom, and 4 oxygen atoms, for a total of 7.
How many atoms in mercury(1) sulfate?
In the formula unit for mercury (I) sulfate, there are two atomic symbols for mercury, one atomic symbol for sulfur, and four atomic symbols for oxygen. This gives a total of seven total atoms.
What is the oxidation number of sulphur in sulfate?
In oxygen containing anions that also include a less electronegative element, oxygen is taken to have an oxidation number of -2. A sulfate ion has a charge of -2. The four oxygen atoms of a sulfate ion have a total charge of 4 X -2 or -8; therefore, the oxygen atom must have an oxidation number of +6 to yield the correct value for the charge of the sulfate ions.
How many moles of Ni are in kg of nickel sulfate?
(NH4)2SO4 so 2 N, 8 H, 1 S, 4 O = 15 total In one mole(unit) of any substance there are 6.022 x 1023 particles. This number is known as Avogadro's number. So for ammonium sulfate there would be 15 times this number = 9.033 x 1024. However, 1 molecular unit of ammonium sulfate contains 15 atoms.
What is the total number of atoms in Chromate?
Total 5 atoms in chromate (1 of Chromium and 4 of Oxygen)

How many atoms of sulfur are in aluminum sulfate?
Aluminium sulfate is Al2(SO4)3 and has two aluminium, three sulphates and 12 oxygens. So there are a total of 17 atoms.
How many atoms in mercury(1) sulfate?
In the formula unit for mercury (I) sulfate, there are two atomic symbols for mercury, one atomic symbol for sulfur, and four atomic symbols for oxygen. This gives a total of seven total atoms.
How many atoms does copper sulfate have?
First it helps to know the chemical formula: CuSO4 The number in the subscripts indicate the number of atoms of an element in the compound. If there is no number, then it is implied that there is only one atom. So, there is one atom of copper, one atom of sulfur, and four atoms of oxygen; for a total of six atoms.

What is the charge of Cr in Cr2O72?
Since oxygen atoms can only accept two electrons, the balance of charges for the overall neutral molecule suggests that the two chromium atoms must each have donated half of the electrons to the oxygen atoms. Therefore, the total number of electrons required for all three oxygen atoms to reach a noble gas configuration is 3 atoms*2 electrons/atom=6 electrons Dividing this up between the two chromium atoms: 6 electrons/2 atoms=3 electrons/atom Therefore, each chromium atom bears a positive charge (since it donated electrons) of 3+.
How many neutrons are in a chromium element?
A typical chromium atoms has 28 neutrons. Because electrons are so small, virtually all of the atomic mass comes from the protons and neutrons. By subtracting the number of protons (equal to the atomic number) from the total atomic mass, the number of neutrons is obtained. For chromium atomic mass- 52 atomic number (number of protons) - 24 number of neutrons 52-24=28
