How many moles are in 1 kg of C2H6O2?

What is the moles of C2H6O2?

Molar mass of ethylene glycol – (12*2 + 1*6 + 16*2) = 62g/mol. so, in 20g we have 20/62 = 0.32 mol. Mole fraction of ethylene glycol = No of moles of ethylene glocal/ Total number of moles. = 0.068 .

How do I calculate moles?

So in order to calculate the number of moles of any substance present in the sample, we simply divide the given weight of the substance by its molar mass. Where ‘n’ is the number of moles, ‘m’ is the given mass and ‘M’ is the molar mass.

Is kg Kmol g mol?

The molecular weight of a substance, also called the molar mass, M, is the mass of 1 mole of that substance, given in M gram. In the SI system the unit of M is [kg/kmol] and in the English system the unit is [lb/lbmol], while in the cgs system the unit of M is [g/mol].

How many moles of electrons are in 1 kg?

Mass of electron = 9.1 x 10-31Kg One mole of electrons = 6.023×1023 Mass of 1 mole of electrons = 6.023×1023 x 9.1 x 10-31Kg We need to find out moles of electrons in 1 Kg Hence out moles of electrons in 1 Kg = 1kg x 1mole/ 6.023×1023 x 9.1 x 10-31Kg =1.825 x 106 moles of electrons.

How many moles are in 1 kg of water?

Now 18g of H20 is equivalent to 1 mole. Hence, 1000g of it would be equal to 1000/18 moles. This comes out be 55.55 moles. Thus 1 kg of water or ice has 55.55 moles of H20.
