A chemist prepares a solution of sodium nitrate (NaNO3) by measuring out 286. umol of sodium nitrate into a 450. mL volumetric f
shusha [124]

Answer:

Concentration of sodium nitrate solution is 0.636 mmol/L

Explanation:

We know, 1micromol=1\times 10^{-3}mmol

So, 286.micromol=(286.\times 10^{-3})mmol=0.286mmol

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

Here solute is NaNO_{3}

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

Hence concentration of NaNO_{3} solution = \frac{0.286mmol}{450.mL}\times 1000=0.636mmol/L

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