The student pours the water out of the measuring cylinder and measures the mass m2 of the
empty measuring cylinder.
m2 = g
• Calculate a second value r2 for the density of water, using your readings from (b), (e)
and (f) and the equation
r2=
• Calculate an average valuerAV for the density of water, using your results for ρ1 and ρ2.
rAV=
