Correct option is B ethyl ethanoate

The following compound is ester R−COO−R ′ and the naming of ester are done on the basis of alkanoate group (R−COO−) and alkyl (R ′ ) combined to form ester.The suffix for ester is "-oate". The full name of ester is like alkyl alkanoate. Thus the name of given compound is ethyl ethanoate.

Be sure to answer all parts. A mixture of CO2 and Kr weighs 47.9 g and exerts a pressure of 0.751 atm in its container. Since Kr
ololo11 [35]

Answer:a)  Mass of CO_2 in mixture = 26.3 grams

b) Mass of Kr in mixture that can be recovered= 21.5 grams

Explanation:

Given :

Total Pressure = pressure of krypton + pressure of carbon dioxide = 0.751 atm

pressure of krypton = 0.231 atm

Thus pressure of carbon dioxide = 0.751 - 0.231 =0.52 atm

As we know:

p=x\times P

where,

p = partial pressure

P = total pressure = 0.751 atm

x = mole fraction

For CO_2

x_{CO_2}=\frac{p_{CO_2}}{P}=\frac{0.52}{0.751}=0.70

{\text {Mass of} CO_2}=moles\times {\text {Molar mass}}=0.70\times 44=30.8g

For Kr

x_{Kr}=\frac{p_{Kr}}{P}=\frac{0.231}{0.751}=0.30

{\text {Mass of} Kr}=moles\times {\text {Molar mass}}=0.30\times 84=25.2g

Total mass = Mass of CO_2 + Mass of krypton = 30.8 + 25.2 = 56 g

Percentage of CO_2=\frac{30.8}{56}\times 100=55\%

a) Thus Mass of CO_2 in mixture =\frac{55}{100}\times 47.9=26.3g

Percentage of Kr=\frac{25.2}{56}\times 100=45\%

b) Thus Mass of Kr in mixture that can be recovered=\frac{45}{100}\times 47.9=21.5g
