# Question #16bfa

##### 1 Answer

If you only go by **60.0 g**, the answer will need **3** sig figs.

When you're dealing with a **decimal number**, try to remember that

*Non-zero digits and zeros that come after them before the decimal are significant*;

In your case, you have **6** and **0** before the decimal, so that's two sig figs right off the bat. By comparison, **060.0** would still have 2 sig figs **before the decimal**, because the first zero does not count.

*If you have non-zero digits***before**the decimal,**all digits**after the decimal are significant;

You only have **1** digit after the decimal, a zero, but because you had a **6** before the decimal, it counts as a sig fig as well.

*If you only have zeros***before**the decimal, only non-zero digits and zeros that come after them are considered significant**after**the decimal.

For example, **0.02** only has *1 sig fig*, because you only have zeros before the decimal, so only the **2** *after* the decimal counts.

At the same time, **0.020** has 2 sig figs, because you have a non-zero digit followed by a zero digit in the decimal portion.

As a conclusion, your answer must have **3** sig figs because **60.0** has 3 sig figs.
