The chemical formula for calcium hydroxide is: Calculate the molar mass of calcium hydroxide. Round your answer to decimal places.

Chemical Formula = Ca(OH)₂

Molar Mass = 74.09 g/mol

Explanation:

The chemical formula for calcium hydroxide is: Ca(OH)₂. We can know that because the calcium ion always has a +2 charge, while the hydroxide ion has a -1 charge.

We calculate the molar mass by adding together the atomic masses of each atom that makes the compound (these can be found in a periodic table):

Molar Mass = Atomic Mass Ca + (Atomic Mass O)*2 + (Atomic Mass H)*2

Molar Mass = 40.078 + (15.999)*2 + (1.007)*2

Molar Mass = 74.09 g/mol

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.
