If you have 0.82 moles of an ideal gas at 49k and a volume of 5.6L what would be the pressure

The pressure of the gas is 0.590 atm.

Explanation:

Pressure of the gas = P

Volume of the gas = V = 5.6 L

Temperature of the gas = T = 49 K

Moles of the gas = 0.82 mole

Using ideal gas equation :

P = 0.590 atm

The pressure of the gas is 0.590 atm.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
