Please help with any that you can:( 1°C if the pressure is 149.3 kPa? How many moles of hydrogen sulfide H2S are contained in a 327.3 mL bulb at 48.

Assume that 453.6 g dry ice is placed in an evacuated 50.0 L closed tank. What is the pressure in the tank in kiloPascals at a temperature of 45°C after all of the CO2 has been converted to gas?

How many grams of gas are present in each of the following cases:
a) 0.100 L of NO at 703 torr and 62°C
b) 8.75 L of CH4 at 278.3 kPa and 843 K
c) 4341 L of BF3 at 2.22 atm and 788 K

Calculate the density of fluorine gas F2 at STP and at 30.0°C and 725 torr.

A liter of methane gas CH4 at STP contains more atoms of hydrogen than does a liter of pure hydrogen gas also at STP. Using Avogadro’s law as a starting point, explain why.

Calculate the volume in liters of each of the following quantities of gas at STP:
6.72 g C2H2
0.588 g NH3
1.47 kg C2H6

Most mixtures of hydrogen gas with oxygen gas are explosive. However, a mixture that contains less than 3% oxygen is not explosive. If enough oxygen is added to a cylinder of hydrogen at 33.2 atm to bring the total pressure to 34.5 atm, is the mixture explosive?

Given that pressure can be measured in several different units, and that 1 atmosphere (atm) = 760 torr = 101.325 kiloPascals (kPa). If the atmospheric pressure is 740 torr, what is the pressure in atmospheres and kilopascals?

A medical laboratory equipment catalog describes the pressure of a cylinder of gas as being 14.82 MPa (1 MPa = 106 Pa). What is the pressure of this gas in atm and torr?

What is the difference between diffusion and effusion?

Graham’s Law describes the rate of diffusion or effusion of a gas, relative to the type of molecule, and can be written as follows: The rate of diffusion of a gas is inversely proportional to the square root of it molecular mass. Write Graham’s Law in equation form.

What mass of nitrosyl chloride (NOCl) occupies a volume of 0.250 L at a temperature of 325 K and a pressure of 113.0 kPa? What is the density of NOCl under these conditions?

Thin films of amorphous silicon for electronic applications are prepared by decomposing silane gas SiH4 on a hot surface at low pressures, according to the following equation:
SiH4 → Si + 2H2
What volume of SiH4 at 130 Pa and 800 K is required to produce a film 10.0 cm by 10.0 cm and 200 Å thick (1 Å = 10-8cm)? Assume that the density of amorphous silicon is 1.9 g/ cm3.
