2.562 g of H2C2O42H2O (s) was obtained and dissolved in enough DI water to form
150.0 mL of solution. What is the concentration of the resulting of H2C2O4 (aq) solution?
in what units?
in grams/liter
2.562g/.150L
17.08g/L
To calculate the concentration of the resulting H2C2O4 (aq) solution, we need to determine the number of moles of H2C2O4 in the given mass and volume of solution.
1. First, we need to calculate the molar mass of H2C2O4·2H2O. The molar mass of H2C2O4 is 90.03 g/mol, and the molar mass of 2H2O is 36.03 g/mol (2 hydrogen atoms in water x 2.02 g/mol + 1 oxygen atom in water x 16.00 g/mol).
Molar mass of H2C2O4·2H2O = (90.03 g/mol) + (36.03 g/mol) = 126.06 g/mol
2. Next, we need to calculate the number of moles of H2C2O4·2H2O using the given mass of the compound.
Number of moles = Mass / Molar mass
Number of moles = 2.562 g / 126.06 g/mol
3. Now, we need to convert the volume of the solution from milliliters to liters.
Volume of solution = 150.0 mL = 150.0 mL * (1 L / 1000 mL)
4. Finally, we can calculate the concentration of the resulting H2C2O4 (aq) solution using the number of moles and volume of the solution.
Concentration (molarity) = Number of moles / Volume of solution
Plug in the values to get the final answer.
