If you add several numbers how many significant figures can the sum have?

The number whose farthest right significant digit determines it. Whatever place that digit is in is the last significant digit in the sum. For example: 433 + 150 + 3.67 + 8000 = 8586.67, but in sig figs this is only 9000, as the thousands digit is the lowest digit that can be represented.

How do you change 0.09425 into 2 significant figures?

That the last number is 5 means you round the second to last one up. This gives you .0943. However, 3 is the last number now, and that doesn't let one round up. So you are at .094. Four is the last number, and it does not allow you to round up. So you are left with the last two digits of .09, which are the two significant figures.


How many significant figures are in temperatures?

Significant figures are basically the amount of digits in a number. E.g. 2.576 has 4 significant figures 32.545 has 5 significant figures Zeroes before the first non-zero digit and after the last non-zero digit are not counted as significant figures. E.g. 0067.4 has 3 significant figures 67.400 has 3 significant figures 0067.400 has 3 significant figures. In case of thermometer measurement of normal temperatures maximum three digits are significant because most of the thermometers indicate one digit after decimal; as 37.4.
