Calculating Molar Mass And Number Of Moles Worked Example Video

Divide your initial volume by the molar volume constant 224 l.

How to find volume in chemistry with moles.

Multiply your mole value by the molar volume constant 224l.
For example if you have mixed 25g of table salt or nacl into 2 liters of water you first need to determine how many moles are in 25g of nacl.
For the hydrochloric acid it is equal to 3646 gmol.

The equation can be rearranged to find the number of moles if the volume of gas at rtp is known.
Find the molar mass of your substance.
The equality of 1.

Many metals react with acids to produce hydrogen gas.
Molar volume at stp can be used to convert from moles to gas volume and from gas volume to moles.
Volume 05 24 12 dm 3.

Converting from volume liters to moles.
Textmol 224.
Textl is the basis for the conversion factor.

Lets assume that it is the hydrochloric acid hcl.
Decide on the mass concentration of your substance you can either input it directly or fill in the.
Remember that 1 dm 3 1 000 cm 3 so the volume is also 12 000 cm 3.

If you dont know the number of moles of solute but you know the mass start by finding the molar mass of the solute which is equal to all of the molar masses of each element in the solution added together.
One mole of nacl has a mass of approximately 585 grams.
To do this multiply the mass of solute you have by its molar mass conversion factor.

To calculate molarity divide the number of moles of solute by the volume of the solution in liters.
