To find the mass of nitrogen gas, you need to know the density of nitrogen gas at the given conditions (typically at STP - standard temperature and pressure). The density of nitrogen at STP is about 1.25 g/L. You can use this value to calculate the mass by multiplying the density by the volume given in milliliters.
To find moles when given mass and volume, you need to first calculate the number of moles using the formula: moles = mass (g) / molar mass (g/mol). Then you find the concentration using the formula: moles / volume (L).
At standard temperature and pressure (STP), the density of hydrogen sulfide (H₂S) is approximately 1.363 grams per liter. This value can be calculated using the molar mass of H₂S, which is about 34.08 g/mol, and the ideal gas law, considering that one mole of gas occupies 22.414 liters at STP. Therefore, the density is derived by dividing the molar mass by the volume at STP.
The density of hydrogen sulfide gas (H2S) at standard temperature and pressure (STP) is approximately 1.363 grams per liter. This value can be derived from the molar mass of H2S, which is about 34.08 g/mol, and the fact that one mole of gas occupies 22.4 liters at STP. Thus, the density is calculated as the molar mass divided by the molar volume.
Knowing the mass and volume of gas at STP (standard temperature and pressure) helps in calculating the number of moles of the gas present, which is useful in chemical reactions and stoichiometry calculations. Additionally, it allows for comparisons between different gases under standardized conditions.
Density is mass per volume. Density of gas is mostly the same in mol/volume. The molecular mass play large role in the different of density. Weak intermolecular force and interaction among different species of gases may give extra additional to the different in density of mix gas but at very small fraction.
At STP, the molar volume of any ideal gas is 22.4 L/mol. To find the density of CCl4 vapor at STP, we need to calculate its molar mass. CCl4 has a molar mass of 153.8 g/mol, so the density of CCl4 vapor at STP would be 153.8 g/mol divided by 22.4 L/mol, which equals approximately 6.86 g/L.

Problem: Calculate the density of CH4 gas at STP. How to solve the problem: Density is mass over volume. (D = M/V), this is what we need to find. Information you will need: Molecular weight of CH4 = 16.05 g/mol STP = Pressure (P) = 1 atm (unit of pressure) and Temperature (T) à 273 K (unit of temperature) Use the ideal gas law. PV = nRT n = mass/ mw (molecular weight- "The molecular weight is essentially the same thing as the molar mass except that, as the name implies, it refers to molecules rather than just elements. The molar mass and molecular weight is typically given in units of grams per mole." - Answers.com) n = unit of mass V = unit of volume PV = (mass/mw) RT Steps: Re-arrange the ideal gas law equation, so that you get M/V (which is density). Mass/V = mw (molecular weight) x P/ RT Mass/V = (16.05 g/mol) x 1 atm / [0.08206 (L)(atm)/ (mol)(K)] (273 degrees K) Because of the gas law constant, atm (unit of pressure), K (unit of temperature) and mol (numerical unit) cancel out, and we are left with units of grams per L (unit of volume), which is what we want. Thus, our answer will be in units of g/L. Plug the equation into your scientific calculator. I got 7.16 x 10^-1 g/L

Nitrogen gas at STP is less dense than xenon gas at STP because nitrogen has a lower atomic mass and thus lighter molecules, leading to lower density. Additionally, xenon is a noble gas with a higher atomic mass and larger atomic radius, contributing to its higher density.
Hydrogen? You need the conditions, pressure and temperature, of the gas. 1 mole of the gas occupies 22.4 liters at STP. The molar mass of hydrogen is 2.0 g/ mole. So the density at STP is 2.0 / 22.4 = 0.0893 g/liter. At any other pressure and temperature you can use the ideal gas law to find the volume of one mole and then find the density.

The mass of the Chlorine will depend upon the density of the Chlorine which depends upon the temperature and pressure of the Chlorine. Assuming stp (standard temperature and pressure) the density of Chlorine is 0.0032 g/ml. density = mass / volume → mass = volume × density = 100 ml × 0.0032 g/ml = 0.32 g.
