How many moles of aluminum ions are present in 0.34 moles of Al2(SO4)3?
IceJOKER [234]

Answer:

We need 0.68 moles of aluminium ions to be present to make 0.34 moles Al2(SO4)3

Explanation:

Step 1: Data given

Number of moles Al2(SO4)3 = 0.34 moles

Step 2: The balanced equation

2Al + 3H2SO4 = Al2(SO4)3 + 3H2

Step 3: Calculate the number of moles aluminium ions

For 2 moles we need 3 moles H2SO4 to produce 1 mol Al2(SO4)3 and 3 moles H2

For 0.34 moles Al2(SO4)3 we need 2*0.34 = 0.68 moles aluminium

We need 0.68 moles of aluminium ions to be present to make 0.34 moles Al2(SO4)3
