Answer:
P = 0.0373 atm
Explanation:
Given data:
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
Answer:
0.01981 gallons.
Explanation:
In this problem, we need to convert 75 mL of water to gallons.
We know that, 1 gallon = 3785.41 mL
To convert 75 mL to gallons, we must use to the unitary method such that,
1 mL = (1/3785.41) gallon
So,

So, there are 0.01981 gallons in 75 mL of water.
