Since, density is directly proportional to mass. So, an ext is the massive of an element much more will it is in its density.
You are watching: Which element has the greatest density at stp
Mass that magnesium is 24.305 g/mol.
Mass that barium is 137.327 g/mol.
Mass the beryllium is 9.012 g/mol
Mass of radium is 226 g/mol.
Hence, radium has an ext mass as such it will have actually the greatest thickness at STP.
Further Explanation:
Ideal gas law is the equation that state for any hypothetical gas. The expression for the ideal gas equation is together follows:
Here,
P is the pressure.
V is the volume.
T is the absolute temperature.
n is the number of moles.
R is the global gas constant.
The formula to calculate the number of moles is together follows:
Here,
n is the number of moles.
m is the mass.
M is the molar mass.
Substitute the value of n indigenous equation (2) in equation (1).
Rearrange equation (3) as follows:
The formula to calculate thickness is together follows:
Here,
m is the mass.
V is the volume.
Substitute equation (5) in equation (4).
Rearrange equation (6) to calculate the density.
At STP, T and P stay constant, R is already a constant. So follow to equation (7), density of substance is straight proportional come the molar fixed of the substance.
The molar mass of scandium is 44.96 g/mol.
The molar fixed of selenium is 78.97 g/mol.
The molar fixed of silicon is 28.09 g/mol.
The molar massive of salt is 22.99 g/mol.
The molar massive of selenium is the highest amongst the given facets so its density will be the greatest.
