After the change of temperature and pressure-> the number of moles of the gas is still the same.
n1=P1*V1/RT1
n2=P2*V2/RT2
R=0.082 constant... you can cancel it out
n1=n2
10C=10+273.15K=283.15K
120c=120+273.15k=393.15
P1*V1/T1=P2*V1/T2
1*0.021/283.15=15*V2/393.15
V2=1.943*10^-3 L = 1.943ml

The temperature of 200 mL of gas
Elden [556K]

Answer:

691.6 torr

Explanation:

Given data:

Initial temperature = 273 K

Initial pressure = 1 atm

Final temperature = -25 °C (-25 + 273 = 248 k)

Final pressure = ?

Solution:

P₁/T₁ = P₂/T₂

P₁ = Initial pressure

T₁ = Initial temperature

P₂ = Final pressure  

T₂ = Final temperature

Now we will put the values in formula.

P₁/T₁ = P₂/T₂

P₂ = P₁T₂/T₁  

P₂ = 1 atm × 248 K / 273 k

P₂ =248  atm. K / 273 K

P₂ = 0.91 atm  

In torr:

0.91  × 760 = 691.6 torr

Place the following aqueous solutions of nonvolatile, nonionic compounds in order of decreasing osmotic pressure. I. 0.011 M suc
dangina [55]

Answer:

I > III > II

Explanation:

The osmotic pressure (π) is a colligative property that can be calculated using the following expression.

π = M × R × T

where,

M is the molarity of the solution

R is the ideal gas constant

T is the absolute temperature

As we can see, there is a direct proportionality between the molarity of the solution and its osmotic pressure. As a consequence, the correct order for osmotic pressures is:

I > III > II
