All of the following choices demonstrates correct rounding

<h3>Further explanation</h3>

There are general rules used in rounding numbers

1. Determine the rounded digit

2. Pay attention to the digits afterward (right). If the digit shows the numbers 0, 1, 2, 3 or 4, then the digit to be rounded is fixed, and the digit on the right is 0

3. If the digit on the right shows the numbers 5, 6, 7, 8 or 9, then the digit to be rounded is added to one, and the digit on the right side is made all 0

for example, In rounding the nearest hundreds number, then we see the digit in the number tens (right of the digit hundreds), if it is worth 0, 1, 2, 3 or 4, then it remains, but if it shows numbers 5, 6, 7, 8 or 9, then the digit to be rounded is added one, and the right-hand side is 0

Choice of answer we add from the problem above:

6,022 × 10²³mol⁻¹

6.0 × 10²³mol⁻¹

6,02214 × 10²³mol⁻¹

For the Avogadro number of 6.0221367 × 10²³mol⁻¹
