A chemist prepares a solution of sodium nitrate (NaNO3) by measuring out 286. umol of sodium nitrate into a 450. mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in mmol/L of the chemist's sodium nitrate solution.

Concentration of sodium nitrate solution is 0.636 mmol/L

Explanation:

We know,

So,

Concentration in mmol/L is defined as number of mmol of solute dissolved in 1000 mL of solution

Here solute is

Total volume of solution = Total volume of volumetric flask = 450. mL

Hence concentration of solution =

So, concentration of sodium nitrate solution is 0.636 mmol/L

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
