25.0 grams Na2SO4 ( only way this compound is possible )
25.0 grams Na2SO4 (1 mole Na2SO4/142.05 grams)
= 0.176 moles Na2SO4
-----------------------------
5,7 moles (SO4)3-.
How many moles are in 4.70g of NH3?
Sulfate (SO4) has an electrovalency of -2
For this you need the atomic (molecular) mass of Fe2(SO4)3. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. Fe2(SO4)3=400.1 grams768 grams Fe2(SO4)3 / (400.1 grams) = 1.92 moles Fe2(SO4)3
The moles number of water 12; the chemical formula is KAl(SO4)2.12H2O.
5,7 moles (SO4)3-.
Al2 SO4(wrong) this is how it should be written Al2(SO4)3This how you do it3.5 moles Al2(SO4)3 x 3 mole Sulfur / 1 moles Al2(SO4)3 = put that in ur calculator it will give u the answer
how many moles of sulfur are present in 3.4 moles of Al2(SO4)3
How many moles are in 4.70g of NH3?
SO4 is the chemical formula for the anion sulfate.
The Sulfate, SO4
Sulfate (SO4) has an electrovalency of -2
That must be the III oxidation state of iron. That is; Fe2(SO4)3 8.27 X 10-6 moles Fe2(SO4)3 (2 moles Fe/1 mole Fe2(SO4)3)(6.022 X 1023/1 mole Fe) = 9.96 X 1018 atoms of iron ------------------------------------
For this you need the atomic (molecular) mass of Fe2(SO4)3. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. Fe2(SO4)3=400.1 grams768 grams Fe2(SO4)3 / (400.1 grams) = 1.92 moles Fe2(SO4)3
SO4
K2(so4)
The moles number of water 12; the chemical formula is KAl(SO4)2.12H2O.
