how many electrons are there in two gram nitrate ion
Asked by Sumeet Sokhey | 31st Jan, 2012, 08:27: PM
Expert Answer:
The molar mass of nitrate ion is 62 g
So, the no. of moles will be= Grams/ molar mass= 2g/62g = 0.0322
Multiply this by Avogadro's number to get the number of atoms.
No. of atoms = 0.0322 X 6.023 X 1023
Multiply this by no. of electrons per nitrate ion to get the number of electrons in 2g of nitrate ion.
No. of electrons in 2 g nitrate ion = 32 X 0.0322 X 6.023 X 1023 = 6.206 X 1023 electrons
