Answer 1

Answer:

Pressure is 76.7 atm

Explanation:

We may use the Ideal Gases Law to solve this problem.

P . V = n . R . T

P is pressure, V is volume (must be in L), n are the moles, R is the Universal Gases Constant (0.082 L.atm/mol.K) and T is absolute T° (T° C + 273), temperature in K.

T = 25°C + 273 = 298 K

P . 0.5L = 1.57 mol . 0.082 L.atm/mol.K . 298K

P = ( 1.57 mol . 0.082 L.atm/mol.K . 298K) / 0.5L =

P = 38.36 L/atm /0.5 L

P = 76.7 atm
