You have dissolved 10 g sodium oxide in 200 ml water.calculate. the concentration of the solution​
mash [69]

0.05M is the concentration of the solution​.

The amount of a chemical substance in a mixture is expressed by the substance's concentration. Concentration can be expressed in numerous ways. In chemistry, the terms "solvent" and "solute" are used to denote the substance of interest and the medium in which it is dissolved, respectively

Subtract the solute's mass from the total volume of the solution. Using m as the solute's mass and V as the total volume of the solution, write out the equation C = m/V. To get the concentration of your solution, divide the mass and volume figures you discovered and plug them in.

C = m / V

C = 10 / 200

C = 0.05M.

Using the phase diagram for water, what phase is water at 0.01 degrees Celsius and 0.0060 atmospheres?
anzhelika [568]
<span>Answer: at 0.01 °C and 0.0060 atm the three phases (solid, liquid and gas)
</span><span>
</span><span>
</span><span>Explanation:
</span><span>
</span><span>
</span><span>1) Water at 0.0060 atm and 0.01° C is at its triple point.
</span>

2) The triple point is the point in the phase diagram at which the three physical states coexist: gas, liquid and solid.

3) That means that water can freeze and boil at the same time. In fact they can happen any of the six changes of phase: freezing (liquid to solid), melting (solid to liquid), evaporation (liquid to gas), condensation (gas to liquid), sublimation (solid to gas), and deposition (gas to solid).

The phase diagram is unique for any substance, meaning that it is different for different substances: the normal boiling and melting points are different.
