Explanation:
The isotope symbol will have the mass number and chemical symbol. The atomic number will be equal to the number of protons because the atomic number is the number of protons in an atom. The electrons will be equal to the protons because the atom is neutral. The neutrons can be found by subtracting the number of protons from the mass number. The mass number can be found by adding the protons and neutrons. It is also in the name of the isotope.
Answer: A pressure of 0.681 atm would be exerted by 0.023 grams of oxygen if it occupies 31.6 mL at
.
Explanation:
Given : Mass of oxygen = 0.023 g
Volume = 31.6 mL
Convert mL into L as follows.
Temperature =
As molar mass of is 32 g/mol. Hence, the number of moles of
are calculated as follows.
Using the ideal gas equation calculate the pressure exerted by given gas as follows.
PV = nRT
where,
P = pressure
V = volume
n = number of moles
R = gas constant = 0.0821 L atm/mol K
T = temperature
Substitute the value into above formula as follows.
Thus, we can conclude that a pressure of 0.681 atm would be exerted by 0.023 grams of oxygen if it occupies 31.6 mL at
.
