A student finds the density of a liquid by measuring its mass and its volume. The following is a summary of his measurements.
mass of empty beaker = (20 ± 1) g
mass of beaker + liquid = (70 ± 1) g
volume of liquid = $(10.0 \pm 0.6)c{m^3}$
He correctly calculates the density of the liquid as $5.0gc{m^{ - 3}}$.
What is the uncertainty in this value?
1 )
$0.3gc{m^{ - 3}}$
$0.5gc{m^{ - 3}}$
3 )
$0.6gc{m^{ - 3}}$
4 )
$2.6gc{m^{ - 3}}$
