1 mole of a gas at S.T.P always has the volume 22.414dm3 so number of moles multiply by 22.414 (molar volume) is equal to total volume at S.T.P , volume at other conditions may be calculated by equation of states, P1V1/T1 = P2V2/T2

What is molar and molal volume?
The molar volume at STP(22.4 L/mol) can be used to calculate the molar mass of the gas.
Explain why the molar volume of a gas at RTP is greater than that of the gas at STP?
At RTP the assumed temperature is 293ºK, at STP the assumed temperature is 273ºK. The formula used for this is Pressure x Volume = moles x ideal gas constant x Temperature. So Volume = (moles x ideal gas constant x temperature) / Pressure Assuming Pressure and moles stays constant... Volume at RTP = ( 1 mole x 8.31451 x 293 K ) / ( 101.325 Pa) Volume at RTP = 24.0429 Volume at RTP = 24.0dm^3 Volume at STP = ( 1 mole * 8.31451 * 273 K ) / ( 101.325 Pa) Volume at STP = 22.4017 Volume at STP = 22.4dm^3
How do you calculate the atomic weight of a metal using its atomic radius and density?
Given the density, you can find the volume per mole of metal by taking dividing the molarity by the density. Using this, you can find the volume of a mole of atoms (this is a different value) by multiplying to the volume per mole of the metal by the packing efficiency. Next, divide the volume of a mole of atoms by the Avagadro's number. Then, using the volume of a sphere, you can find the radius. Here's a better explanation using formulas: Volume per mole of metal = Molarity/Density Volume per mole of atoms = (Volume per mole of metal) x (Packing Efficiency) Volume of 1 atom = Volume per mole of atoms/6.022 x 1023 Volume of 1 atom = (4/3) x pi x radius3
How is a mole used to indirectly count the number of particles of matter?
A mole contain 6,022 140 857.10e23 atoms or molecules or ions.
What does a mole measure?
An instrument can not be used to measure moles because moles is the amount of grams of a substance divided by the molar mass of the substance. This can not be measured and has to be calculated.
What is volume used for?
Volume is to make sound get louder or softer.
What is molar and molal volume?
The molar volume at STP(22.4 L/mol) can be used to calculate the molar mass of the gas.
What are units conversions used for?
Unit conversions express an amount in a different unit.
What is a mole used in chemistry as?
Mole is a unit of concentration in SI; a mole is equal to the molecular mass of a compound.
Is mole removal done with lasers?
Laser or IPL is usually used for removing flat and pigmented moles. This method of mole removal may require about 3 treatments to make the mole invisible. The laser beam or pulsed light is selectively absorbed by the pigment of the mole, which is then destroyed and shed away.
What is the formula used in conversions?
It depends on what you want to convert.
What is what is graduated cylinder and how it is used?
to make an accurate liquid volume
Runescape Can a cannon be used in mole tunnels?
No, since it wont hit the mole.
What type of energy conversions is used to make a car go down the street?
Energy stored in gasoline is converted to heat, then to the kinetic energy of the car.

What is the SI unit used to measure the number of representative particles in a substance?
its the mole.
