In order to find molarity, the moles of citric acid must be given. Since there was no equation given, I cannot help you find the answer for a 2 liter solution since the base molarity or moles used is not provided. However, I will post an example of how to find the answer you're looking for. You will need to use the following equation to find your definite answer:
(molarity of concentrated)(volume of concentrated)=(molarity of diluted)(volume of diluted)
Step-by-step explanation:
Some key points about the equation given:
- volume will always be in liters
- concentrated would be the original molarity and volume of citric acid that was given. If no volume was given, you were most likely given moles. In this case to find volume use the following equation: molarity = (moles/volume) where volume will be the variable you're solving for which will turn into the next equation of: (moles/molarity) = volume
- volume of diluted will be 2
