Question

the total number of protons electrons and neutrons in 2.4g of sulphur

Answer 1

Answer:

1.2*Na

Explanation:

No. of protons=no. of electrons=16

No. of neutrons= Mass number-Atomic number=32-16=16

no. of moles in 2.4g of sulphur = 2.4/32= 0.075

then atoms in mole = 0.075*Na (Na= avagadro number)

then no. of protons=no. of electrons=no. of neutrons= 0.075*16*Na

                                                                                    =1.2*Na
