consider the fo9rmula for Al2(SO4)3,which is used in perspirants:
a. how many moles of sulfur are present i 3.0 moles of Al2(SO4)3
b. ow many moles of aluminum ions are present in 0.40 mole of Al2(SO4)3
for a and b i multiplied by 6.02*1023 power andgot
science (chem) -
No need to count atoms/molecules.
In 3.0 moles, there are 9.0 moles of S
In .40 moles, there are .80 moles of Al ions
