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
Dry alum refers to the hydrated potassium aluminum sulfate compound that is used to fix pigments on a surface. Its density is 0.752 kg/m3.
As a solid (dry ice) the density is around 1.56 kg/litre, or 1560 g/litre. The density at 0'C in its gas form is around 1.98 g/litre. So the density of CO2 in gas from is around 800 times less dense.
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 ==
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
In the SI system the unit of density is kilograms per cubic meter.
Density = mass / volume
density = mass / volume
Density = Mass/ Volume
density = mass/volume
Density = mass/volume ============================
Density = Mass/Volume.
