A chemist adds 1.45 L of a sodium carbonate solution to a
reaction flask. Calculate the millimoles of sodium carbonate the chemist
has added to the flask. Round your answer to 2 significant digits.

To calculate the millimoles of sodium carbonate added to the flask, you need to use the formula:

Given the concentration is and the volume is , you can calculate the moles:

Since millimoles (mmol) are times the number of moles, you convert this to millimoles:

So, the chemist has added of sodium carbonate to the flask.

Did you know that sodium carbonate, also commonly known as soda ash or washing soda, has historical roots dating back to ancient Egypt? It was first produced from the ashes of plants, and its chemical properties made it essential for creating glass, soap, and detergents throughout history!

If you’re working on calculations like this, double-check your units! One common mistake is forgetting to convert liters to milliliters when the final answer needs to be in millimoles. Keep track of your conversions, and make the calculations easier for yourself!
