What is the molar mass of #Ca_3(PO_4)_2#?

Answer 1

Can you tell me the molar mass of ATOMIC calcium, phosphorus, and oxygen?

In fact you can do this, because you do have access to a Periodic Table, and the atomic masses are printed on the Table. All scientists use the Table daily to assign molecular masses.

And the atomic mass of calcium metal is #40.1*g*mol^-1#, of phosphorus it is #31.00*mol^-1#, of oxygen it is #15.99*g*mol^-1#.
And to determine the molecular mass, all I do is appropriately sum these atomic masses: #(3xx40.1+2xx31.0+8xx16.00)*g*mol^-1#, and what do you get?

To find the molar mass of Ca₃(PO₄)₂, you need to sum the molar masses of each individual element in the compound. The molar mass of Ca is approximately 40.08 g/mol, P is approximately 30.97 g/mol, and O is approximately 16.00 g/mol.

Ca₃(PO₄)₂ contains 3 calcium atoms, 2 phosphorus atoms, and 8 oxygen atoms.

So, the molar mass is:

3(Ca) + 2(P) + 8(O) = 3(40.08) + 2(30.97) + 8(16.00) = 120.24 + 61.94 + 128 = 310.18 g/mol.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
