Web18 sep. 2024 · Thus, $\dfrac{1}{{9.108 \times 6.022}} \times {10^8}$ moles of electrons will weigh one kilogram. How many moles are in 1 kg of water or ice? Here is another simple explanation: First convert the mass in kg to g ( 1kg=1000g). 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 ... Web(i) Mass of an electron = 9.1 x 10 -28 g Or 9.1 x 10 -28 g contains = 1 electron Therefore 1g contains = 1/9.1 x 10 -28 *1 = 1.098 x 10 27 electrons (ii) We know, one mole of electron = 6.022 x 10 23 electron Mass of one electron = 9.1 × 10 –28 g Or mass of 6.022 x 10 23 electron = 9.1 x 10 -28 x 6.022 x 10 23 = 5.48 x 10 -4 g
