Question

define isopes and isobars with example.if one mole of carbon atom weight 12 grams what is the mass of one atom carbon​

Answer 1

Answer:

ISOTOPES: Element having same atomic number but different atomic masses. OR Elements having same number of neutron but different number of proton.

ISOBARS: Atoms of different elements that has same number of nucleons. OR Each of two or more isotopes of different elements, with the same atomic weight.

ANSWER: As we know that 1 mole of carbon contains 6.02×10^23atoms. Therefore we can write the mass of 6.02×10^23atoms=12g. Hence, the mass in gram of 1 atom of carbon is 1.993×10^-23g.
