two. Here are some rules for determining sigfigs:
eg.
NUMBER SIG FIGS EXPLANATION453 kg3All non-zero digits are always significant.5057 L4Zeros between 2 sigfigs are significant.5.003Additional zeros to the right of decimal and a sigfigs are significant.0.0071Placeholders are not significant
2.35 has 3 sig figs.
There are 3 sig figs.
3
3
Two of them
in addition/subtraction you use the most number of sig figs. So in this case you need 5 sig figs in the answer.
4,500 has two significant figures.
Because some part of your equation has a figure that limits how many sig figs you can use. Remember the number of sig figs is symbolic of how precise the initial measurements were. For example the number 2.4 is not as precise as 2.45298. So your answer can only be as precise as the LEAST precise measurement you have taken or been given. So in my example above if 2.4 is the least precise measurement then you can only have an answer with two sig figs.
