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

0.00324 or in scientific notation 3.24×10^-3

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
