What is the concentration of sodium phosphate contains 0.60 M Na+?
I'm not sure what to do and how to figure how to do this question.
0.60 M Na^+.
There are 3 Na atoms in 1 Na3PO4 molecule; therefore, (Na3PO4) must be 0.60/3 = 0.20M Na3PO4.
To find the concentration of sodium phosphate, we need to know its formula and the molar mass of sodium phosphate.
The formula for sodium phosphate is Na3PO4, which means it contains three sodium ions (Na+) for every one unit of sodium phosphate (PO4).
The molar mass of sodium phosphate (Na3PO4) can be calculated as follows:
- The molar mass of sodium (Na) is 22.99 g/mol.
- The molar mass of phosphorous (P) is 30.97 g/mol.
- The molar mass of oxygen (O) is 16.00 g/mol.
So, calculating the molar mass of sodium phosphate:
Molar mass of Na3PO4 = (3 x molar mass of Na) + molar mass of P + (4 x molar mass of O)
= (3 x 22.99 g/mol) + 30.97 g/mol + (4 x 16.00 g/mol)
= 69.00 g/mol + 30.97 g/mol + 64.00 g/mol
= 163.97 g/mol
Now, to determine the concentration of sodium phosphate, we need to know the number of moles of sodium ions present in 0.60 M Na+.
Given that Na+ concentration is 0.60 M, this means there are 0.60 moles of Na+ in 1 liter (or 1000 mL) of solution.
Since there are three sodium ions (Na+) in one unit of sodium phosphate (Na3PO4), it means that each mole of Na3PO4 provides three moles of Na+ ions.
Therefore, the concentration of sodium phosphate (Na3PO4) can be calculated as:
Concentration of Na3PO4 = (0.60 moles of Na+) / (3 moles of Na+ per mole of Na3PO4)
= 0.20 M Na3PO4
Thus, the concentration of sodium phosphate is 0.20 M Na3PO4.
To find the concentration of sodium phosphate, we need some additional information. The concentration of sodium phosphate can be determined by knowing the stoichiometry of the compound and the concentration of one of its ions (in this case, Na+).
The chemical formula for sodium phosphate is Na3PO4. From the formula, we can see that for every one molecule of sodium phosphate, three sodium ions (Na+) are present.
Given that the concentration of Na+ is 0.60 M, we can use this information to find the concentration of sodium phosphate.
Since one molecule of sodium phosphate contains three Na+ ions, the concentration of sodium phosphate (Na3PO4) will be three times the concentration of Na+.
Therefore, the concentration of sodium phosphate (Na3PO4) containing 0.60 M Na+ can be calculated as follows:
Concentration of Na3PO4 = 3 x Concentration of Na+
= 3 x 0.60 M
= 1.80 M
Hence, the concentration of sodium phosphate is 1.80 M.
