By applying Dalton's law of pressure equations we can calculate the total pressure of a mixture of gases by adding together the partial pressures of the component gases
Explanation:
Dalton's law of partial pressure is the concept used in calculating either partial pressure or total pressure in a given mixture of gases.
The law says that each gas has its own pressure which it puts on the mixture of gases. This pressure is called partial pressure. Also, the sum total of all the gases exerting pressure on the mixture is termed total pressure.
The quantity of individual gas can be known and hence it will get easy to calculate its partial pressure.
The relation used is:
Partial pressure = mole fraction of the one gas from mixture x total pressure in the mixture.
It also says that total pressure is equal to:
total pressure = p1 +p2+p3....pn
here p1, p2 is partial pressure of one of gases in mixture.
Answer:
Part 1: W = 116 Y = 163
Part 2: Since 232 is the mailing point of 2 kg then you would divide 232 by 2 to get the melting point for 1 kg, the same with Y.
The pH of the finsl solution is equal to <u>2.93</u>
Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.
C₁ = 0.170 m
V₁ = 17 ml = 0.017 L
C₂ = 0.170 M
V₂ = 22 ml = 0.022 L
C₁V₁ =C₂V₂
0.170× 0.017 L = 2.89 × 10⁻³ ------------- HCl
0.170× 0.022 L = 3.74 × 10⁻³ ------------ NaOH
⇒ 3.74 × 10⁻³ - 2.89 × 10⁻³ = 0.85 × 10⁻³
⇒ 3 + log 0.85
⇒ 3 + -0.07
⇒ pH = <u>2.93</u>
The concentration of an solution is a degree of the amount of solute that has been dissolved in a given amount of solvent or solution. A focused solution is one which has a rather huge amount of dissolved solute.

The addition of sodium chloride to pure water causes the conductivity to INCREASE. The more NaCl present in the water, the higher the conductivity is because NaCl is an electrolyte. Once dissolved in water, it becomes Na and Cl which are corpuscles that conduct electricity.
