What does avagadros law say about a gas at STP?
1 mol of any gas has a volume of 22.4 L at STP
What is the importance of avagadros number?
it is the exact number of paricles of a substance in a mole on the substance. it is also the conversoin number of amu to grams
How do you calculate the mass in grams of 6.073 molecoles of water?
You divide the 6.073 by 6.022x1023 (avagadros number) to get the moles, then multiply by molecular mass (18) to get mass in grams
3.612x1023 molecules is how many moles?
Avagadros number states that there are 6.0221415 x 1023 atoms in a mole so 3.612 x 1023 molecules is just over half a mole 0.525 moles
How many molecules in a mass of 3.9mg of C27H46O?
The molecular weight of it is 386.654g/mol. Convert mass to grams (i.e. 0.0039g). divide mass by molec weight to get 1.0083573x10^-5 moles. Multiply this by avagadros number to get the amount of molecules. this gives you 6.072x10^18 molecules.
What does avagadros law say about a gas at STP?
1 mol of any gas has a volume of 22.4 L at STP
What are the molar conversions between moles and representative particles?
avagadros number
What were amedeo avagadros hobbies?
the wild thingermabober lives in peter schmaltz's ps3
How many molecules in one liter of air at 294.11 degrees Kelvin at one atmosphere of pressure?
Ideal gas law: PV=nRT. number of moles is 0.0414335 moles. x avagadros number is 2.495x1022 molecules
How many molecules are 1.94 moles?
multiply that number by avagadros number, 6.02x10^23
Units of avagadros number?
Avagadros number is 6.02 x 10^23. That is a measurement for converting representative particles or formula units to molecules.
What units do you use to measure atomic mass?
A mole (mol). You can convert to kilograms using Avagadros number.
How do you calculate atoms?
As in number? No of atoms = avagadros number (6.02X10^23) times number of mole of atoms
What is 6.0210 to the 23rd power molecules?
Avagadros number - The number of molecules/element that are found in one mole of the substance
What is the importance of avagadros number?
it is the exact number of paricles of a substance in a mole on the substance. it is also the conversoin number of amu to grams
How many grams of FeCl3 does 5.88 X1028 weigh?
I don't have a good calculator, but i'll talk you through (will actually benefit you to do it yourself, this will come back to bite you if you don't learn it). Avagadros number is no. molecules per mole. 5.88x1028 / avagadros number gives your amount of moles. Moles / molecular weight gives weight
How much is a mole?
A mole is equal to 6.022 x 1023. This number is called Avagadros number. A mole is generally abreiviated as "n".
