Question

Given: d = 2.2 g/L, T = 15°C + 273 = 288 K, P = 3.0 atm, R = 0.0821 L atm/mol K. What is the value of R?

1) 0.0821 L atm/mol K
2) 0.0821 mol atm/L K
3) 0.0821 atm L/mol K
4) 0.0821 mol K/atm L

Answer 1

The value and units for R are 0.0821 L atm/mol K, which are used for calculating properties of gases when using the ideal gas law with pressure in atmospheres, volume in liters, amount in moles, and temperature in kelvins.

Step-by-step explanation:

The question you have asked revolves around the ideal gas law constant, R. The correct value and units for R, as provided in your question, are 0.0821 L atm/mol K. This value is used when performing calculations involving the ideal gas law where the pressure is given in atmospheres (atm), the volume in liters (L), the amount in moles (mol), and the temperature in kelvins (K). It's important to always use consistent units across all variables when working with the ideal gas equation (PV=nRT), which relates the pressure (P), volume (V), temperature (T), and number of moles (n) of a gas.
