Solution :-
Q3 )
Mass of water = (mass of water + beaker ) – mass of beaker
Mass of water trial 1 = 417.86 g – 145.50 g = 272.36 g
Mass of water trial 2 = 366.48 g – 145.50 g = 220.98 g
Q4 ) density of water is 1.0 g per ml
Volume = mass / density
Volume in trial 1 = 272.36 g / 1 g per ml = 272.36 ml
Volume in trial 2 = 220.98 g / 1.0 g per ml = 220.98 ml
Q5) 1 ml water = 1 ml gas
Trial 1 = 272.36 ml water * 1 ml gas / 1 ml water = 272.36 ml gas
Trial 2 = 220.98 ml water * 1 ml gas / 1 ml water = 220.98 ml gas
Q6) water vapor pressure = 18.7 mmHg
Barometric pressure = 756.81 torr
Pressure of O2 gas trial 1 = barometric pressure – vapor pressure of water
= 756.81 torr – 18.7 torr
= 738.11 torr
Pressure of O2 gas trial 2 = = barometric pressure – vapor pressure of water
= 756.81 torr – 18.7 torr
= 738.11 torr
Q7) temperatures
Trial 1 = 21 C +273 = 294 K
Trial 2 = 21 C + 273 = 294 K
