Explanation:
Answer: 1 mol of potassium phosphate.
Explanation:
Find the molar mass of potassium phosphate.
Equation of potassium phosphate = K3PO4
The molar mass of K = 39.10 g/mol, P = 30.97 g/mol, O = 16.00 g/mol (use periodic table for these values).
Then add them up together based off of the equation.
3(39.10 g/mol) + 30.97 g/mol + 4(16.00 g/mol) = 212.27 g/mol
Multiply the 212.26 grams by the molar mass (unit conversion method).
= 1.00 mol
There is 1 mol of potassium phosphate.
Answer:
V = 15.6 L
Explanation:
Hello there!
In this case, according to the definition of molarity in terms of the moles of solute divided by the volume of the solution, it is possible for us to write:
Thus, given the moles and concentration of the solution, we can find the volume as shown below:
V=n/M
Therefore, we plug in the given data to obtain:
V = 2.5mol /(0.16mol/L)
V = 15.6 L
