The value of R is calculated by considering a 1 mole of a gas at STP (T = 0
o
C or 273.15 K, P = 1 atm or 760 mmHg or 101325 Pa and molar volume is 22.4 dm³ or 22.4 litres). From this information, the value of R is?
8.314 J/K/mol
0.08205 J/K/mol
0.08205 J
8.314 J
Which of the gas laws do the graphs represent?
Charles’ law
Dalton’s laws
Boyle’s Law
Avogadro’s laws
375 cm³ of a gas has a pressure of 770 mmHg. What is the new volume if the pressure is reduced to 750 mmHg?
835 cm³
385 cm³
358 cm³
385 dm³
Charles’ law can be represented as?
V
