A compound contains 25.93% N and the rest is oxygen. What is the empirical formula for the compound?
Mnenie [13.5K]

Answer: NO2

Explanation:

                                  N                                O

Divide each by its    25.93                       74.07

mass number              14                             16

                                     2                              4

Divide both by the       2                               2

smaller (i.e. 2)               1                                2

Therefore, the empirical formula = NO2

Given the starting solution had a concentration of 1.25 m, how many moles of co[h2o]6cl2 were available in the amount of startin
siniylev [52]
Molarity of solution is defined as number of moles present in one liter solution. Mathematically, it is expressed as 
Molarity = \frac{\text{number of moles}}{\text{volume of solution(l)}}

Thus, if 1 mole of solute is present in 1 liter solution, molarity of solution is 1 M.

In present case, initial conc, of solution was 1.25 M.

∴ Number of moles of <span>co[h2o]6cl2  available initially = 1.25 mole, if the solution is 1 liter</span>

At 850K, 65L of gas has a pressure of 450kPa. What is the volume (in liters) if the gas is cooled to 430K and the pressure decre
Novosadov [1.4K]

Answer:

V₂ =  45.53 L

Explanation:

Given data:

Initial temperature = 850 K

Initial volume = 65 L

Initial pressure = 450 KPa

Final temperature = 430 K

Final pressure = 325 KPa

Final volume = ?

Solution:

Formula:  

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

Solution:

V₂ = P₁V₁ T₂/ T₁ P₂  

V₂ = 450 KPa× 65 L × 430 K / 850 K × 325KPa  

V₂ = 12577500 KPa .L. K / 276250 K. KPa

V₂ =  45.53 L
