Question

what variable determines which
\ value you use in your calculation?
moles (n)
volume (v)
temperature (t)
pressure (p)

Explanation:

The gas constant \( R \) has different values based on the units of pressure (e.g., \( 0.0821 \, \text{L·atm/(mol·K)} \) for atm, \( 8.314 \, \text{J/(mol·K)} \) for Pascals). Thus, pressure (P) determines which \( R \) value to use.

Answer:

pressure (P)
