Answer:
3 cm3
Explanation:
1 L = 1 dm3 = 1000 mL (or 10^3 mL)
1 dm = 10 cm
1 dm3 = 10^3 cm
==> 1 mL = 1 cm3
Therefore, 3 cm3 = 3 mL
Answer:
liquid's heat of vaporization = 38.4 kJ/mol
Explanation:
given data
vapor pressure P1 = 6.91 mmHg
at temperature = 0 °C = 273.15 K
boiling temperature = 105 °C
solution
for vapor pressure and temperature we get here
P2 = 760.0 mmHg
T2 = 68.73°C = 378.15 K
we use here the Clausius-Clapeyron Equation that is
ln = .................1
put here value
In
solve it we get
x = 38445 J/mol
liquid's heat of vaporization = 38.4 kJ/mol

Answer : The new volume of was, 5.17 L
Explanation :
Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles of gas.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Therefore, the new volume of was, 5.17 L
