Describe the process used to determine how many atoms of each element are in 2Ca3(PO4)2. Show all
your work.

Answer 1

Six atoms of calcium, four of phosphorous and sixteen of oxygen for a total of twenty six

Step-by-step explanation:

Hello there!

In this case, according to the molecular formula of the two moles of calcium phosphate:

`2Ca_3(PO_4)_2`

Thus, in order to calculate the atoms of each atom, it is necessary to multiply the two in front of the formula by the subscripts in the reaction:

`atoms Ca=2*3=6\\\\atoms P=2*2=4\\\\atoms O=2*2*4=16`

Thus, we obtain six atoms of calcium, four of phosphorous and sixteen of oxygen for a total of twenty six.

Best regards!
