What is the "true" volume? A student calibrated a eudiometer by first recording the mass of the empty eudiometer followed by filling the eudiometer to the 50.00 mL line with deionized water at 22°C, but the measurement came to around 50.21mL. The mass of the water is 49.771g. The density of water @ 22 Celsius is 0.997770g/mL. What's the true volume?
