138 g/mol

Explanation:

There is some data missing. I think the original question is:

A sample of an unknown compound is vaporized at 130 °C. The gas produced has a volume of 960 mL at a pressure of 1.00 atm, and it weighs 3.99 g.

Assuming the gas behaves as an ideal gas under these conditions, calculate the molar mass of the compound. Round your answer to 3 significant digits.

First, we can find the moles of the gas using the ideal gas equation. (Absolute temperature 130 + 273 = 403 K)

The molar mass of the compound is:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
