## 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.

## How many moles are in 1 kg of oxygen?

so,**62.5 moles** of oxygen have (6.022×10^23×62.5) molecules. Hence 1 kg of oxygen has (376.38×10^23) molecules.

## How grams are in a kilogram?

Kilograms to Grams conversion

1 kilogram (kg) is equal to **1000 grams** (g).

## How many atoms does c2h6o2?

Ethylene glycol is composed of **6 hydrogens, two carbon, and two oxygen atoms**.
