See the answer below.

Work Step by Step

a) At 100$°C$, boiling is taking place: bubbles of vapor are emerging from the liquid, so the glass will be slightly wet inside due to condensation to maintain the thermodynamic equilibrium. b) Approximately 1 atm, since this is the normal boiling point of water. c) Assuming all water is liquid: $10\ g\div0.958\ g/cm^3=10.44\ cm^3$ d) Assuming water vapor behaves like an ideal gas: $n=1\ atm×0.050\ L/((0.082)(373\ K))$ $n=0.00163\ mol$ Mass: $0.00163\ mol×18.015\ g/mol=0.0294\ g$
