Question

Xenon is an element similar to Neon. Its density can be found on the Reference Table. Convert Xenon’s density to scientific notation.

Answer 1

The Scientific Notation of Xenon’s density : 1.31293 × 10²

Further explanation

Scientific Notation consists of 2 parts

1. the first part: the first digit followed by the decimal point

2. The second part: the power of 10 which shows the number of digits after the decimal point

Xenon's density = 131.293

First digit = 1, then we give the decimal point and the next digit

The power of 10 is determined from the number of decimal points moved from the original decimal point

Because we move the decimal point two digits to the left, the power of 10 has the number 2 (10²)

So that the Scientific Notation form becomes:

1.31293 × 10²
