Problem
A student has three 100.0 mL samples of H₂O, each in a different phase under the indicated conditions.
• Sample A: ice at 0 °C (density = 0.917 g mL⁻¹)
• Sample B: liquid water at 25 °C (density = 0.997 g mL⁻¹)
• Sample C: water vapor at 100 °C and 1 atm (assume ideal-gas behavior; density = 5.9 × 10⁻⁴ g mL⁻¹)
Which sample contains the greatest mass of H₂O?
(a) Samples A and B contain equal masses greater than Sample C
(b) Sample B only
(c) Sample A only
(d) Sample C only
