A sample of an unknown compound is vaporized at 150.°C . The gas produced has a volume of 960.mL at a pressure of 1.00atm , and
it weighs 0.941g . Assuming the gas behaves as an ideal gas under these conditions, calculate the molar mass of the compound.
1 answer:
Answer:
34.02 g.
Explanation:
Hello!
In this case, since the gas behaves ideally, we can use the following equation to compute the moles at the specified conditions:
Now, since the molar mass of a compound is computed by dividing the mass over mass, we obtain the following molar mass:
So probably, the gas may be H₂S.
Best regards!

Answer:
336.04 cm
Explanation:
T1 = 60+273 = 333K
T2 = 100+273 = 373K
V2 = (V1×T2)/T1
V2 = 300×373/333
V2 = 336.04 cm
Answer:
- The nucleus of the atom as suggested by "nuclear" chemistry.
- Radioactive element are generally very large due to both their high number of protons, neutrons, and electrons.
- An excessive amount of protons or neutrons.
- Periodic table, table O, and table N.
- Personal opinion question.
- The atomic number.
- It represents the number of protons, and can also represent the number of electrons in a neutral atom (an atom with no charge).
- Protons ---- element.
- Random, self-generated.
- Gamma radiation is the only thing on table O that is mass less. Close to being the same is Beta particles which have almost no mass.
- Neutrons and Gamma radiation.
- Gamma radiation.
- Electrons and Beta particles.
- To turn one element into the isotope of another. Yes, I believe it is aptly named because you are changing the identity of the element.
- The number of protons because they are what define the identity of an element.
Goodluck!
