Partial a because the liquid flow ate in the air
Hey there!
For this we can use the combined gas law:
We are only working with pressure and temperature so we can remove volume.

P₁ = 2 atm
T₁ = 27 C
P₂ = 2.2 atm
Plug these values in:

Solve for T₂.




Convert this to kelvin and get 302.85 K, which is closest to B. 330 K.
Hope this helps!
Answer:
that the second one surely represent the beta particle
Answer:
The mass of 1.26 mole of water, H₂O, is 22.68 grams
Explanation:
Molar mass is the amount of mass that a substance contains in one mole. In other words, the molar mass of an atom or a molecule is the mass of one mole of that particle and its unit is g/mole.
In this case, being:
the molar mass of water H₂O is:
H₂O= 2*1 g/mole + 16 g/mole= 18 g/mole
Then you can apply the following rule of three: if 18 grams are present in 1 mole of H2O, how much mass is present in 1.26 moles of water?

mass= 22.68 grams
<u><em>The mass of 1.26 mole of water, H₂O, is 22.68 grams</em></u>
Cool liquid from 314 K to 273 K, freeze liquid at 273 K, and cool solid to 263 K.
