Question

What is the value of R in the ideal gas law?

O A. 0.0821 L-atm/mol-K
O B. -0.0821 L-atm/mol-K
O C. 273 L'atm/mol-K
O D.-273 L'atm/mol-K

Answer 1

A. 0.0821 L-atm / mol-K

Step-by-step explanation:

Ideal gas law is given as,

PV = nRT

R is termed as Universal gas constant.

Under standard conditions of Temperature (273 K) , Volume (22.4 L), pressure (1 atm) and for number of moles (n=1 ), we will get R as,

R = 1 atm * 22.4 L/ 1 mol * 273 K

= 0.0821 L-atm / mol-K
