The key to solving this problem is density. Density determines the mass of a molecule for a certain volume. Kia is given a beaker containing 100 g which volume is at <span>100 mL mark. Then the density of the liquid would be:
</span>density=mass/volume
density= 100g/ 100ml= 1g/ml
If t<span>he water now comes up to the 50 mL mark, then the weight would be:
</span>density = mass/volume
mass = volume * density
<span>mass = 50ml * (1g/ml)= 50g</span>
Answer:
Perfectly Specified
Explanation:
Pressure, P = 0.9 atm
Boiling point = T
Number of components C = 1
Number of phases P = 2
Using Gibbs phase rule as:
F = C - P + 2
F = 1 - 2 + 2 = 1
At Pressure = 0.9 atm, boiling point is T which means that the temperature is also fixed which is equal to 96.7 °C . The data taken from steam table.
In given problem, the pressure is fixed so temperature is also fixed.
The system is perfectly specified.

<span>Hydrogen ion, strictly, the nucleus of a hydrogen atom separated from its accompanying electron. Thehydrogen nucleus is made up of a particle carrying a unit positive electric charge, called a proton. The isolated hydrogen ion, represented by the symbol H +, is therefore customarily used to represent aproton.</span><span>
