Achemist adds 180.0 ml of a 1.42m sodium carbonate (na co,) solution to a reaction flask. calculate the millimoles of sodium carbonate the chemist has added to the flask. round your answer to 3 significant digits. mmol

The millimoles of sodium carbonate the chemist has added to the flask are 256

Explanation:

Molarity is defined as the number of moles dissolved per liter of the solution.

To calculate the number of moles for given molarity, we use the equation:

    .....(1)

Molarity of solution = 1.42 M

Volume of solution = 180.0 mL

Putting values in equation 1, we get:

Thus the millimoles of sodium carbonate the chemist has added to the flask are 256.

its first and third is your answer i did the qustion the fourth isnt right
