Answer :
(a) The number of sulfur atoms are, .
(b) The mass of the mass of is, 1059.682 grams.
(c) The number of moles of is,
(d) The mass of the mass of is,
Explanation :
(a) As we are given the number of moles of is, 1.75 mole. Now we have to calculate the number of sulfur atoms.
In the , there are 2 iron atoms, 3 sulfur atoms, 12 oxygen atoms.
As, 1 mole of contains
number of sulfur atoms.
So, 1.75 mole of contains
number of sulfur atoms.
The number of sulfur atoms are,
(b) As we are given the number of moles of is, 2.65 mole. Now we have to calculate the mass of
.
The molar mass of = 399.88 g/mole
The mass of the mass of is, 1059.682 grams.
(c) As we are given the mass of is, 3.45 grams. Now we have to calculate the moles of
.
The molar mass of = 399.88 g/mole
The number of moles of is,
(d) As we are given the formula unit of is, 3. Now we have to calculate the mass of
.
As we know that 1 mole of contains
formula unit.
Formula used :
Now we have to calculate the mass of .
The molar mass of = 399.88 g/mole
The mass of the mass of is,
