Answer:
23.76g
Explanation:
To solve for the mass of carbon dioxide (CO2), let us first obtain the number of mole of CO2.
From the question, the following were obtained:
V = 8.13L
P = 204kPa = 204000Pa
Recall: 101325Pa = 1atm
204000Pa = 204000/101325 = 2atm
T = 95°C = 95 + 273 = 368K
R = 0.082atm.L/K/mol
n =?
PV = nRT
n = PV /RT
n = 2 x 8.13/ 0.082 x 368
n = 0.54mole
Now let us convert 0.54mole of CO2 to gram. This is illustrated below:
Molar Mass of CO2 = 12 + (16x2) = 12 + 32 = 44g/mol
Number of mole of CO2 = 0.54mole
Mass of CO2 =?
Number of mole = Mass /Molar Mass
Mass = number of mole x molar Mass
Mass of CO2 = 0.54 x 44
Mass of CO2 = 23.76g
Potassium is a chemical element

Answer:
<em>The correct option is A) DNA → RNA → protein</em>
Explanation:
Central Dogma can be described as the process under which the processes of transcription and translation are focused. It is the process by which particular parts of DNA or particular genes make up the specified proteins which are required.
The conversion of DNA into RNA is known as transcription. This process occurs in the nucleus. The conversion of mRNA into proteins is termed as translation. This process occurs in the ribosomes of the cytoplasm.
Answer:
35.50
Explanation:
There are two stable isotopes, 35Cl (75.77%) and 37Cl (24.23%), giving chlorine a standard atomic weight of 35.45
