Alarge weather balloon requires plenty of helium gas in order to ascend into the atmosphere to take measurements. if the balloon has a volume of 100,000 liters, about how many moles of helium gas would be required to fill the balloon to a pressure of 1 atm and a temperature of 27 degrees c? a. 531 moles b. 1394 moles c. 4063 moles d. 5280 moles

the answer is either b or c

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.
