How much energy is released when 2.65kg of diethyl ether ((c2h5)2o) freezes? the heat of fusion for diethyl ether is 7.27 kj/mol.

M=2.65kg=2650g
M=74g/mol

n = m/M = 2650g/74g/mol ≈ 35.81mol

Heat of fusion = 7.27kJ/mol

If            7.27kJ  energy is in   1mol
than           x        energy is in   35.81mol

x = [35.81mol*7.27kJ]/1mol = 260.3387kJ

Atomicity occurs to prevent updates of the database occurring only partially, which can cause greater problems than rejecting the whole series outright.some are monatomic, diatomic, triatomic etc because it shows the number of atoms. for example, monatomic means it contains only one atom.

Adozen is 12, and your needing to calculate the weight of one medium egg, so i would do 21/12=1.75 per egg, and check your answer by doing 1.75 * 12= 21 : ) : ): ): ): ) i hoped i
