Question

calculate total number of electron in 5 gram of CaCo 3​

Answer 1

Answer:

Explanation:

for electron in caco3 ca+c+3(o)) = 20+6+3(8) = 50electrons

number of electron = number of proton = 50

Atomic mass of caco3 is 100.0869 g/mole ~ 100g/mole

there for neutron un caco3 = atomic mass - number of electrons

=100.0-50 = 50
