sure. we know that the molarity of gas in a constant temperature and pressure (exp, room temperature, 25 celcius, 1 atm) will have a constant volume. in 25'c, 1 atm, the volume of one mole of gas is 24.5 L. so that if we know the volume of the gas, we can divide it by 24.5, such that we can determine the molarity of that gas. and molarity times molar mass will equal to the mass of a type of gas.
calculation : given a known volume V at 25'c , 1atm
no of mole of gas = v / 24.5 = q mole of gas.
mass of gas = q(no of mole of gas) x Mr(molecular mass of that type of gas)
*assumption : it is a pure gas (contain the same type of gas), and we also know the type of gas we are testing( so that we know the molecular mass of that gas)
method 2:
1) weight the mass of a balloon(p).
2) pump the gas/ gasses into the balloon, weight the mass of the balloon +gasses(q).
3) p-q = weight of the gasses
* disadvantages : we cannot define the mixture of gasses inside the balloon.
* since we got analytic chemistry, we can put the gasses into a nuclear magnetic resonance spectorscopy and analyse the substance inside the balloon because of chemial shift.
What else can I help you with?
Quantity of a gas is measured in?
The quantity of a gas is typically measured in moles, which is a unit of measurement that represents the amount of a substance. Another common unit for measuring the quantity of a gas is liters, which represents the volume of the gas.
How do you know gas has mass?
Gas has mass because individual gas particles are composed of atoms or molecules that have mass. While gas particles are very spread out and move randomly, they still have mass due to the mass of the atoms or molecules they are made of. This mass can be measured using scales or other experimental methods.
How is the process of finding the mass of gas different from that of finding the mass of liquid?
The process of finding the mass of a gas typically involves using a gas syringe or a balance while the gas is contained in a closed system, as gases can expand and fill their container, making them more difficult to weigh directly. In contrast, finding the mass of a liquid usually involves placing it in a container on a balance, where the liquid's weight can be measured directly. Additionally, gases are often measured under specific conditions of temperature and pressure, while liquids are generally measured at a consistent state without the same variabilities.
What is mass measured on?
Mass is typically measured using a balance or a scale, which compares an object's weight to that of a standardized mass. The unit of mass is the kilogram (kg) in the metric system, and the pound (lb) or ounce (oz) in the imperial system.
What is molecular mass of pure gas?
The molecular mass of a pure gas is the sum of the atomic masses of all the atoms in its molecule. It is typically measured in atomic mass units (amu) or grams per mole (g/mol). The molecular mass is useful for calculating other properties of the gas, such as density or molar volume.
Does gas have definite mass?
Yes, gas has mass. The mass of a gas is determined by the number of gas particles present and the type of gas molecules. The mass of gas can be measured using a balance or by determining the mass of the container before and after the gas is added.
Does gas have weight?
Yes, gas has weight because it is made up of molecules that have mass. The weight of gas can be measured using a scale or by calculating the mass of the gas.
The molar mass of a gas can be determined from?
for Apex: can be found easily from the periodic table is the mass of a mole of the gas
Quantity of a gas is measured in?
The quantity of a gas is typically measured in moles, which is a unit of measurement that represents the amount of a substance. Another common unit for measuring the quantity of a gas is liters, which represents the volume of the gas.
How do you measure the density of a gas?
The density of a gas can be measured by determining its mass per unit volume. This is typically done by measuring the gas's pressure, temperature, and volume and using the ideal gas law to calculate the density. Alternatively, specialized instruments such as densitometers can be used for more accurate measurements.
How do you know gas has mass?
Gas has mass because individual gas particles are composed of atoms or molecules that have mass. While gas particles are very spread out and move randomly, they still have mass due to the mass of the atoms or molecules they are made of. This mass can be measured using scales or other experimental methods.
What unit is the mass of a plane measured in?
Mass is measured in kilograms.
Can you weigh gas?
Gas cannot be weighed in the traditional sense because it is a form of matter that does not have a fixed volume or mass. Instead, gas is typically measured by its volume or pressure.
What are properties of mass?
The property of mass is NOT a measure of how heavy an object is
Why is mass measured in?
Because the same amount of gas will always weigh the same while the volume will vary with pressure.
What can volume mass and weight be measured by?
Volume is measured with pipettes, liquid or gas counters, burettes, cylinders, calibrated recipients etc.Mass is measured with all types of balances.For weight, in physics weight = mass x gravitational acceleration.
Mass is measured with what?
Mass is measured with a Triple Beam Balance. Yes it is.
