Question

Mass of one atom of an element is 8 x 10-24 g.
This is equal to
(1) 4.8 u
(2) 48 u
(3) 0.048 u
(4) 0.48 u​

Answer 1

Answer:

0.048u is the correct answer

Answer 2

Hello Dear,

◆ Answer - (1)

Mass = 4.818 u

◆ Explaination -

Here, conversion factor is -

1 g = 6.022×10^23 u

Now mass of element is represenred as -

Mass = 8x10^-24 g

Mass = 8×10^-24 × 6.022×10^23 u

Mass = 4.818 u

Hence, mass of element is represented as 4.818 u.

Thanks dear. Hope that is useful..
