Question

Estimate the number of electrons in 10g of water and find charge on them.

Answer 1

Answer:

Explanation:

no. of moles of water =given mass / molar mass = 10/18 = 5/9 moles

total no. of atoms in 10g of water = 6.022 × 10^23 × 5/9 = 3.455 × 10^23atoms

no. of electrons in 1 atom of H2O = 2 × 1 +8 = 10

total no. of elctrons = 3.455 × 10^23 × 10 = 3.455 × 10^24 electrons..

charge in 1 electron = 1.6 ×10^-19

charge carried by 3.455 × 10^24

electrons = 1.6 × 10^-19 × 3.455 ×10^24 = 5.528 × 10^5
