Calculating density of unknown liquid from flask mass measurements

[benworld]

Homework Statement

A 10.00 mL volume of unknown liquid was added to stoppered erlemeyer flask, which weighed 48.217 g. If weigh of the unknown liquid plus the stoppered flask was 57.056 g. Calculate density of unknown to correct number of signifigent figure.

Homework Equations

D = m /v


3. The Attempt at a Solution [/b

D = m / v

v = 10.00 ml

m = 57.056 - 48.217 = 8.839 g

d = 8.839 g / 10.00 ml = 0.8839 g/ml

Answer is 0.8839 g/ml

is this correct ? or should I round it to 0.884 g/ml ]

Seems correct, but what is that about a "signifigent figure"?

I actually believe that it would be .88. With sig figs you round to the lowest amount of sig figs found in the given information. In this problem it would be the 10.00 mL, the 0 after the decimal are just place holders, insignificant.
