How many particles are in 3.4 moles of HCl?
Answer:
The volume is 77 L.
Explanation:
where P is pressure, V is volume, n is moles, R is the gas constant, and T is temperature in Kelvins.
The current STP temperature is 0∘C or 273.15 K (used for gas laws), and the pressure is 105Pa, which most people write as 100 kPa (both pressures are equal).
