The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume.
Answer:
0.031 parts per million
Explanation:
80 micrograms/m^3 = 80 micrograms/m^3 × 1m^3/1000L = 0.08 micrograms/L
Concentration in parts per million = concentration in micrograms/L × molar volume/MW
Concentration in micrograms/L = 0.08
Molar volume at 25°C and 101.325kPa (1 atm) is 24.45L
MW of SO2 = 64g/mole
Concentration in ppm = 0.08×24.45/64 = 0.031 ppm
The process involving separation of liquid/solid mixture as regards this question is Decantation.
- Decantation can be regarded as one of the process used in separation of liquid from solid as well as other immiscible (non-mixing) liquids through the removal of the liquid layer that is present at the top from the layer of solid/liquid which present at the below.
- In the process, the liquid will be poured slowly into another vessel as the pouring continues, then the solid will settle in the original vessel.
- This process can be done through tilting the mixture after the the top layer have been poured out.
<em>Therefore, decantation is one of the separation technique.</em>
