## Homework Statement

I just wanted to know if I wrote the answer with the correct number of significant figures for this addition problem.

0.00015 M + 0.00004 M + 0.00011 M = 0.00030 M (Correct?)

## Homework Equations

See above.

0.00015 M + 0.00004 M + 0.00011 M = ?

## The Attempt at a Solution

See Part 1.

All of the original numbers have 5 decimals places, but only the first and third values have 2 significant figures. (The second has 1 significant figure.) Therefore, the final answer must be expressed with 5 decimal places, and will have 2 significant figures (0.00030 M)?

Thank you.
