Student question: You have a 100 mL solution of 0.02 M sodium carbonate (Na2 CO3 ). You are given the following information:
Your answer: To work with this 0.02 M sodium carbonate (Na2CO3) solution, you can follow these steps:
Step 1: Calculate the moles of Na2CO3 in the solution.
To do this, use the formula:
Moles = Molarity × Volume (in L)
Moles = 0.02 M × 0.100 L (since 100 mL = 0.100 L)
Moles = 0.002 mol Na2CO3
Step 2: Utilize the information given in the problem.
As you haven't provided any additional information, you can now use the 0.002 moles of Na2CO3 in the 100 mL solution for your further calculations or reactions, depending on the context of your problem.
