ghazi · Answer

well find the molarity, use w/m*100/v

ghazi · Answer

$$M=\frac{ w }{ m }*\frac{ 1000 }{ V }=\frac{ 100 }{ 310 }*\frac{ 1000 }{ 200 }=1.6129 M$$

ghazi · Answer

this is your concentration

anonymous · Answer

can you identify where center numbers came from.

ghazi · Answer

well w-- weight of calcium phosphate that is given and is equal to 100g 
m-- molar mass of calcium phosphate= 310g
v-- volume of solution 200ml :D :D

ghazi · Answer

@Lanik  does that help?

anonymous · Answer

what about the 1000

ghazi · Answer

well its in the formula of finding molarity that is why i have written 1000 ml its a reference in molarity formula

anonymous · Answer

okay
