Since the container of the gas is rigid, the volume of the gas will remain constant. Therefore, when the number of particles were decreased in half then the pressure will also be half of the original given they both are subjected to the same temperature.
PV = nRT
V, T and R are constants so they can be lumped together to a constant k.
P/n = k
P1/n1 = P2/n2
since n2 = n1/2
P1/n1 = P2/<span>n1/2</span>
P2 = P1/2
The correct answer is 230 mmHg.
When liquid water boils at 100°C, the water vapor pressure is 760 mmHg
Hence, when liquid water boils at 50°C, the water vapor pressure is (760/2) mmHg or 230 mm Hg.
As the boiling temperature of water halves so does the vapor pressure of water. This is in accordance to Pressure Law.
According to Pressure law, pressure is directly proportional to the absolute temperature, at constant volume.

I hope I'm right
To convert grams to moles, we need the molar mass of carbon. this can be founded in the periodic table.
molar mass of C= 12.0 g/mol
38.1 g C (1 mol C/ 12.0 grams)= 3.18 moles of C
28) All elements are made of atoms
29)Protons and Neutrons
-Electrons make up the outside of the Nucleus
