How many moles of phsophorus, oxygen and calcium atoms are contained in 1/2 a mole of Ca3(PO4)2?

I said:


1.5 moles of Ca


1 mole of P


4 moles of O





Am I right?

How many moles of phsophorus, oxygen and calcium atoms are contained in 1/2 a mole of Ca3(PO4)2?
Yes , you are right





3 atomes of Ca by molecule


so in 0.5 mole --%26gt;3*0.5 = 1.5 mole Ca





2 atomes of P by molecule


so in 0.5 mole --%26gt;2*0.5 = 1.mole P





8 atomes of O by molecule


so in 0.5 mole --%26gt;8*0.5 = 2 moles O
Reply:1mol Ca3(PO4)2





3 atoms Ca You are going to multiply the amount of atoms by


2 atoms P 1/2 because since there is 1 mol of the whole


8 atoms O compound, or you could to divide them by 1/2 :)





3/1 x 1/2 = 3/2 or 1.5


2/1 x 1/x = 1/1 or 1


8/1 x 1/2 = 8/2 or 4
