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 ]
