4.6 k
7.2 k
61 k
96 k

Using R as 8.314 J / mol. K.

P = 175kPa, = 175 000Pa = 175 000 N/m²,  V = 275mL = 275 cm³ = 275 * 10⁻⁶ m³,  n = 0.80 mole,  T = ?

By ideal gas equation:

PV = nRT

175000 * 275 * 10⁻⁶  = 0.8 * 8.314 * T

T =    (175000 * 275 * 10⁻⁶) / (0.8 * 8.314 )

T = 7. 2355

T ≈ 7.2 K

This is beautiful. I hope this helps you. God bless you!
