Answer:
The vapor pressure in solution is 0,0051 atm
Explanation:
This is the formula for vapor pressure lowering, the colligative property.
P vapor = Pressure sv pure . Xsv
Where Xsv is data.
Xsv means Molar fraction (moles solvent/total n° moles)
Vapor pressure of water, pure is 17.5 mmHg
P vapor = 0,0313 atm . 0163
P vapor in solution = 0,0051 atm
Molar fraction does not have units
A solution will have less vapor pressure than that observed in the pure solvent.
By applying ideal gas equation,
[tex]P\times V=n\times R\times T[\tex]
Where, P= pressure of gas
V=volume of gas
R=Gas constant
n=Number of moles of gas
T=Temperature
At STP, each gas has a defined value of pressure, volume and temperature.
P= 1 atm
R=0.0821 L atm mol⁻¹ K⁻¹
T= 0°C or 273 K
Putting all the values in the equation will give:
[tex]1\times V=0.98\times 0.0821\times 273[\tex]
V = 22 L
So the answer is 22 L.
Charle's law states the relationship between the temperature and the volume of the gas. The final volume occupied at 120 °C is 0.20 L.
<h3>What is Charle's law?</h3>
Charle's law is the ideal gas law that states the relationship between the volume of the gas occupied at a temperature.
Given,
V1 = 0.75 L
T1 = 1443 .15 K
T2 = 393.15 K
The final volume is calculated as:
(V1 × T2) ÷ T1
= 0.75 × 393.15 ÷ 1443.15
= 0.20 L
Therefore, 0.20 L is the final volume.

Answer:
100%
Explanation:
If all labels in the square are “t” then there is no way that the plants will not be tall. Therefore there is a 100% chance the plant will be tall.
