Question

An electron has an atomic mass of 5.4 x 10-4. If a carbon atom has 6 electrons, what is the combined atomic mass of the electrons in a single Carbon atom? Answer in scientific notation.

Answer 1

Answer:

0.00324 or in scientific notation  3.24×10^-3

Step-by-step explanation:

MASS OF SINGLE ELECTRON = 5.4×10^-4

MASS OF 6 ELECTRONS = 6× 5.4×10^-4

                                           =32.4×10^-4

                                            = 3.24×10×10^-4

                                             = 3.24×10^-3
