Answer:
1.08 grams
Explanation:
first, we need to find the number of moles
we divide 12.1/22.4=0.54 moles
we multiply the number of moles with the molecular mass 0.54x2=1.08g
A heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it. The plateaus on the curve mark the phase changes. The temperature remains constant during these phase transitions.
Answer:
4046atm
Explanation:
For this question you can use the ideal gas law,
<em />
<em />
Where P is pressure, V is volume, n is moles of substance, R is the constant, and T is the temperature.
Because of the units given, R will equal .08026
<h3>Rearrange the equation to solve for pressure:</h3>

Then, plug in the values (I'll be excluding units for simplicity, but they all cancel out for pressure in atm):

This will give you:

Prokaryotes are organisms whose cells lack a nucleus and other organelles
