Density = mass divided by volume (mass/volume)
Example: A block of wood weighs 3.5 kg (or 3,500 grams)
It is 9 cm x 4 cm x 55 cm (9 x 4 x 55 = 1,980 cm3)
3500/1980 = 1.768 grams/ cm3
The density of dry alum is approximately 1.36 grams per cubic centimeter.
The density of carbon dioxide gas is lower than the density of solid dry ice because solid carbon dioxide (dry ice) is more compact and has a higher density due to its solid state. Dry ice is about 1.5 times denser than gaseous carbon dioxide.
The formula to calculate the density of water for a change in temperature is: Density = Density at reference temperature / [1 - β (T - T_ref)], where β is the volumetric thermal expansion coefficient of water, T is the temperature, and T_ref is the reference temperature.
To calculate the average molar mass of dry air, we can use the ideal gas law. Given that the density of dry air is 1.17 g/L at 21°C and 740.0 torr, we can calculate the molar mass using the formula: Molar mass = (dRT)/(P), where d is the density, R is the ideal gas constant, T is the temperature in Kelvin, and P is the pressure. Substituting the values and units, we can find the average molar mass of dry air.
To properly use a pycnometer for measuring the density of a substance, first clean and dry the pycnometer. Then, weigh the empty pycnometer and record the mass. Fill the pycnometer with the substance, making sure there are no air bubbles. Weigh the filled pycnometer and record the mass. Calculate the density using the formula: density (mass of substance)/(volume of pycnometer).
That depends on the type and grade of the sand
Air dry density
== Density== Mass/ Volume ==
In the SI system the unit of density is kilograms per cubic meter.
Bulk density = dry weight / volume, then by knowing the dry weight and bulk density we can calculate the volume.
Maximum value of dry density of river sand is 1.7 gm/cc
Density = Mass/ Volume
Density = Mass/Volume.
density = mass / volume
Density = mass / volume
density = mass/volume
