How many moles of hydrogen are in 4.70 moles of C12H22O11

103.4 moles of hydrogen

Explanation:

Given data:

Moles of C₁₂H₂₂O₁₁ = 4.70 mol

Number of moles of hydrogen present = ?

Solution:

one mole of C₁₂H₂₂O₁₁  contain 22 moles of hydrogen. Thus in order to determine total number of moles in 4.70 moles of C₁₂H₂₂O₁₁ we will multiply the 22 moles of hydrogen with 4.70 moles of C₁₂H₂₂O₁₁.

1 mole of C₁₂H₂₂O₁₁ = 22 moles of Hydrogen

4.70  × 22 moles

103.4 moles of hydrogen

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.

it is stable as it is in group 0 which have full outer shells of electrons
