To determine the mass of Malonic Acid (C3H4O4) in a solution, we can use the formula:
mass = volume × concentration × molar mass
Given:
Volume of solution = 10.0 mL
Concentration of solution = 0.200 M
First, let's convert the volume from milliliters to liters:
10.0 mL = 10.0 × 10^-3 L = 0.010 L
Next, we need to find the molar mass of Malonic Acid (C3H4O4):
Molar mass of C = 12.01 g/mol
Molar mass of H = 1.01 g/mol
Molar mass of O = 16.00 g/mol
Molar mass of C3H4O4:
(3 × 12.01 g/mol) + (4 × 1.01 g/mol) + (4 × 16.00 g/mol) = 72.04 g/mol
Now we can calculate the mass of Malonic Acid:
mass = volume × concentration × molar mass
= 0.010 L × 0.200 mol/L × 72.04 g/mol
≈ 0.144 g
Therefore, the mass of Malonic Acid present in 10.0 mL of a 0.200 M solution is approximately 0.144 grams.
To determine the mass of Malonic Acid (C3H4O4) present in 10.0 mL of a 0.200 M solution, we need to follow these steps:
Step 1: Calculate the number of moles of Malonic Acid using the molarity and volume.
Step 2: Convert the moles to grams using the molar mass of Malonic Acid.
Let's start with Step 1:
1. Calculate the moles of Malonic Acid using the molarity and volume:
Molarity (M) = moles of solute / liters of solution
Convert the volume from milliliters (mL) to liters (L):
10.0 mL = 10.0 mL * (1 L / 1000 mL) = 0.0100 L
Now we can use the molarity and volume to find the moles of Malonic Acid:
Moles = Molarity * Volume
Moles = 0.200 mol/L * 0.0100 L
Step 2: Calculate the mass of Malonic Acid using the moles and molar mass.
2. Determine the molar mass of Malonic Acid (C3H4O4):
Molar mass of C = 12.01 g/mol (carbon)
Molar mass of H = 1.008 g/mol (hydrogen)
Molar mass of O = 16.00 g/mol (oxygen)
Add up the molar masses of all the atoms in the compound:
Molar mass of C3H4O4 = (3 * 12.01 g/mol) + (4 * 1.008 g/mol) + (4 * 16.00 g/mol)
Now we can calculate the mass:
3. Calculate the mass of Malonic Acid:
Mass = Moles * Molar mass
Finally, plug in the values we obtained in the previous steps:
Mass = (0.200 mol/L * 0.0100 L) * [(3 * 12.01 g/mol) + (4 * 1.008 g/mol) + (4 * 16.00 g/mol)]
By performing the calculation, you will get the mass of Malonic Acid in grams.
