Well, honey, a number with 22 zeros is called a "sextillion." It's like a trillion, but with a whole lot more zeros to impress your friends with. Just don't go spending that imaginary money all in one place now!

When is zero not significant science?

In scientific measurements, a zero is not considered significant when it serves merely as a placeholder in a whole number, such as in 1200, where the trailing zeros do not indicate precision. Additionally, a zero at the beginning of a decimal, like in 0.0025, is also not significant. However, zeros between non-zero digits, such as in 105, or trailing zeros in a decimal number, like in 2.500, are considered significant. Understanding the context and the placement of zeros is crucial for accurately interpreting the precision of measurements.


How many significant figures does 0.0072 contain?

It has 4 significant figures.Significant Figuresà Non-zero numbers are always significant figures.à Zeros are tricky:- If zeros appear before a non-zero (called leading zeros), they are NEVER significant (ex: 0.025)- If zeros fall between non-zero numbers, they are ALWAYS significant (ex: 205)- If zeros come at the end of the number, they WILL be significant only IF there is a decimal present (ex: 250.0)à Exact numbers (or counting numbers) have infinite significant figures. For example, if we count 3 pencils, we know there are exactly 3 pencils. Or, when we say 1 inch = 2.54 cm, we know this is for exactly 1 inch.


What is the advantage of using scientific notation to express numbers that are very small and very large?

Less digits are needed but they still have the same numerical values.
