The radius of a hydrogen atom is 0.0000000529177 of a millimeter. Express this number as an approximation (1 point)
0.0000005
0.00000005
0.0000000063
0.00000006
The correct approximation is 0.00000005.
To express the radius of a hydrogen atom as an approximation, we need to round the number 0.0000000529177 to a more convenient value.
Looking at the digits after the decimal point, the next digit is 6, which is greater than 5. This means we should round up.
Therefore, the approximation for the radius of a hydrogen atom is 0.00000006.
To express the given number as an approximation, we need to look at the digits beyond the five digits provided in the question.
In this case, we have 0.0000000529177. The next digit is 9, which is greater than 5, so we round up the last digit we are keeping (7) by adding 1. Therefore, the approximation becomes 0.00000006.
So the correct answer is 0.00000006.
