P = 0.0373 atm

Explanation:

Given dа ta:

Mass of krypton = 1.86 g

Volume of krypton = 17.5 L

Temperature of krypton = 190 F

Pressure of krypton = ?

Solution:

First of all we will calculate the number of moles.

Number of moles = mass / molar mass

Number of moles = 1.86 g / 83.9 g/mol

Number of moles = 0.022 mol

Formula:

PV = nRT

P = nRT / V

P = 0.022 mol * 0.0821 atm. L. mol⁻¹. K⁻¹ * 360.928 K / 17.5 L

P = 0.652 atm. L / 17.5 L

P = 0.0373 atm
