Question

how many electron protons and neutrons are present in 3.0g of ethane​

Answer 1

Answer:

3.0g ethane = 1/10 mole ethane1 mole ethane = 18 mole electron = 18 mole proton = 12 mole neutron Therefore, 1/10 mole ethane will have1.8 mole electron = 1.8×6.02×10^23 electrons1.8 mole proton = 1.8×6.02×10^23 protons1.2 mole neutron = 1.2×6.02×10^23 neutrons
