Answer:
Molar mass= 78.8gmol-1
Explanation:
P= 550torr, V= 0.0732dm3, m= 0.5g , R= 8.314, T= 273+489= 762K
Applying
PV= m/Mm×(R×T)
Substitute and Simplify
Mm= 78.8gmol-1
Answer:
Explanation:
Hello,
In this case, we are able to perform this unit conversion by cubing the relationship between inches and centimetres as shown below:
Best regards.
Answer:
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. The scientific study of crystals and crystal formation is known as crystallography.
Explanation:
To make any substance solid, molecules must come very close to each other. Substances with weak intermolecular forces have weak bonding. Hence to make their molecules come close to each other, we must provide low temperature.
