Density. water's density is always 1 g/ cm^3
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:
Nitrile, amide, carboxylic acid, phenyl (aka. arene)
**There are so many functional groups, so I may list some you don't know. There may also be some that I am not aware of. However, these are all the ones I can see.**
Explanation:
Nitrile: (bottom-left) N triple bonded to C
Amide: (middle) N single bonded to 3 carbons
Carboxylic Acid: (bottom-right) C-CO2H
Phenyl: (top-right) six carbon ring with alternating double bonds
