PLEASE HELP

A physicist discovers an element whose atom has a mass of 0.00000000000000112 grams. He makes an entry in his journal and writes the mass in scientific notation as
_____ E _____.

Answer 1

Answer:1.12e-15 g, or 1.12*10^-15 g.

Explanation:

Answer 2

1.12e-15

Explanation:

Scientific notation is a way of writing very large number or very small number in the small notation.

In which the exponent is equal to the number of times the decimal point must be moved to produce a number between 1 and 10.

When we move the decimal in right side the exponent is negative and when we move it to the left side it is positive.

Here, the given quantity is,

0.00000000000000112 grams

Its scientific notation =
`1.12* 10^(-15)`

Since, we can write
`10^(\pm a)=e\pm a`

Thus, scientific notation of the quantity 0.00000000000000112 is 1.12e-15.
