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.

i can ! i just need to know what the paragraph is! : p

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation

this is not my own answer, this is an answer for the same question by the user blahblahmali. i do not claim ownership of this account.
