What is the concentration of a solution with a volume of 1.5 liters containing 560 grams of calcium phosphate (Ca3(PO4)2)?

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

catya your not at all which answer i've seen you do this on another question!
