How many particles are in 3.4 moles of HCl?

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).

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.
