## How many moles of electrons weigh 1kg?

1 kg will contain = 1(9.108×10−31)×(6.022×1023) moles of electrons. Or, 1 kg will contain = 19.108×6.022×**108 moles** of electrons. Thus, 19.108×6.022×108 moles of electrons will weigh one kilogram.

## How many moles are in 1 kg?

The idea here is that 1 kg-mole is equal to **103 moles**. This is the case because a mole of a substance must contain a number of particles of that substance equal to the number of atoms present in exactly 12 g of carbon-12.

## How many electrons are there in 1 kg?

How many electrons are there in 1 kg? Answer: **1.8×10^6 moles of electrons** weigh 1 kg.

## How many moles of electrons weigh 7Kg?

**1.825 x 10^6 moles** of electrons.

## How many moles of protons will weigh 200g?

Therefore, **200 moles** of proton will weigh 200gm.

## 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 many moles will be there in 1 kg of water?

This comes out be **55.55 moles**. Thus 1 kg of water or ice has 55.55 moles of H20.

## What is the molarity of 1 kg of water?

= **55.56 M**. Thus, the molarity of the water is 55.56 M.

## How many protons would make 1 kg?

Answer: Mass of proton (m) = 1.67×10^(-27) kg. N = 6×10^(**23**) (approx.) Exact mass of proton gives N = 6.022 x 10^(23).

## How many electrons would make 1 kg if the mass of an electron is 9.1 10/31 kg?

Answer: Given : mass of an electron=9.11 x 10⁻³¹kg =9.11 x 10⁻²⁸g 1kg=1000g Number of electrons present in 1kg will be : =1000/9.11 x 10⁻²⁸ =109.76 x 10 ²⁸ ∴ Number of electrons present in 1kg would be **109.** **76x 10²⁸ electrons**.

## How many electrons are in 1kg of iron?

In the one-kilogram iron weight there are 1.08·10^{25} atoms, which corresponds to the chemical amount of approximately 17.9 moles of atoms. In total there are **2.8·10 ^{26} electrons** and 8.6·10

^{25}of them are valence.
