What is the molecular weight of O2?
The molecular weight of O2 (oxygen gas) is approximately 32 g/mol.
How to convert 10 ppm mole of H2O to ppm wt in natural gas?
To convert ppm mole of H2O to ppm wt in natural gas, you need to know the molecular weight of water (H2O), which is 18 g/mol. Once you have this information, you can use it to convert between the two units. This conversion involves considering the molecular weight of the components in the mixture.
What is the molecular weight of a gas that diffuses 1.414 times faster than a nitrogen molecule?
The rate of diffusion of a gas is inversely proportional to the square root of its molecular weight according to Graham's law. Since the gas diffuses 1.414 times faster than nitrogen, its molecular weight must be approximately 1.414 times smaller than that of nitrogen, which is approximately 28 g/mol. Therefore, the molecular weight of the gas is around 19.8 g/mol.
How do you calculate density from molecular weight?
Density can be calculated from molecular weight using the formula density = (molecular weight) / (molar volume). Molar volume is the volume occupied by one mole of the substance and can be calculated using the ideal gas law or experimental data. Dividing the molecular weight by the molar volume gives the density of the substance.
Why density of carbon di oxide is greater than that of ammonia gas?
The density of a gas is dependent on its molecular weight and the mass of the gas particles. Carbon dioxide (CO2) has a higher molecular weight compared to ammonia (NH3) due to the presence of heavier carbon atoms. This higher molecular weight of CO2 contributes to its greater density compared to ammonia gas.
Chlorine diffuses 2.04 faster than gas Q Find molecular weight of gas Q?
To find the molecular weight of gas Q, we can use Graham's law of diffusion. The rate of diffusion is inversely proportional to the square root of the molecular weight. Since chlorine diffuses 2.04 times faster than gas Q, we set up the equation (rate of Q)/(rate of Cl2) = sqrt(Molecular weight of Cl2 / Molecular weight of Q), then solve for the molecular weight of gas Q.

Is the Volume gas directly proportional to its molecular weight?
No, the volume of a gas is not directly proportional to its molecular weight. The volume of a gas is mainly influenced by the number of gas molecules present, temperature, and pressure. The ideal gas law equation, PV = nRT, takes into consideration these factors to describe the relationship between volume, pressure, temperature, and the amount of gas.
How much did poison gas weigh?
The weight of poison gas can vary significantly depending on its chemical composition. For example, chlorine gas has a molecular weight of about 35.5 g/mol, while phosgene has a molecular weight of approximately 98 g/mol. Generally, gases are measured in terms of their density relative to air, which has an average molecular weight of about 29 g/mol, rather than a specific weight. Thus, the weight of poison gas is context-dependent and varies with the specific type of gas in question.
What's lighter nitrogen or natural gas?
Technically, atomic nitrogen has less mass than a molecule of methane (CH4 = natural gas) with the former having a mass of 14 and the latter a mass of 16.04. However, in nature, nitrogen exists in its molecular form consisting of two nitrogen atoms. Thus, molecular nitrogen has a molecular weight of 28 vs. 16.04 for methane, making a molecule of atmospheric nitrogen heavier than one of methane. This translates into a density difference as follows: N2 density = 1.251 g/L at STP (standard temperature and pressure) CH4 density = 0.717 g/L at STP Final note: "Natural Gas" is not actually 100% methane. It has a variable composition consisting of 70-90% methane, 5-15% ethane (C2H6) and trace amounts of propane, butane, and other gases.

How do you find molecular mass if specific volume is given?
To find the molecular mass if specific volume is given, you can use the ideal gas law. The ideal gas law relates the pressure, volume, temperature, and the number of moles of gas to the gas constant. By rearranging the ideal gas law equation and solving for the molecular mass, you can determine the molecular mass of the gas.
How quickly gas spreads in air?
The diffusion rate of gas in air depends on factors like temperature, pressure, and molecular weight of the gas. Gases with lower molecular weight tend to diffuse faster than those with higher molecular weight. In general, gas molecules will spread throughout the air relatively quickly due to their high mobility and ability to mix freely.

Carbon dioxide (CO2) has a higher molecular weight compared to ammonia (NH3) due to the presence of heavier carbon atoms.

Which gas is heavier than each other?
The one with the highest molecular/atomic weight.
