Energy for vacancy formation in silver?
equilibrium number of vacancies at 800 degree Celsius is 3.6 x 1023m-3. density = 9.5g/cm3 Mr = 107.9 g/mol

How will you calculate the density of a substance?
volume/mass= density
How do you calculate gas density?
density = mass/volume
How to calculate NaCl density?
The density can be measured experimentally.
What is the formula to calculate density?
density = mass/volume
How would you calculate the density if the object is cube?
The shape of an object is not enough to calculate its density. You also need its mass and then Density = Mass/Volume.
What is needed to calculate the density of a graduated cylinder?
Mass and volume are needed to calculate the density of a graduated cylinder.
How do you calculate volume if given bulk density?
Bulk density = dry weight / volume, then by knowing the dry weight and bulk density we can calculate the volume.
