How many molecules of carbon monoxide gas can be produced from 395 grams of oxygen gas ?

The answer for the following problem is mentioned below.

Explanation:

Given:

mass of the oxygen gas = 395 grams

We know;

For the production of the carbon monoxide;

The equation is,

Before balancing the equation;

C + → CO

After balancing the equation;

2 C + → 2 CO

where,

C = carbon molecule

O = oxygen molecule

CO = carbon monoxide

For the equation,

  32 grams of oxygen gas   →  2 × 6.023 × 10^-23 molecules

        395 grams of oxygen gas   →    ?

      =

   = 148.125 × 10^-23 molecules of the carbon monoxide

Therefore 148.125 × 10^-23 molecules of the cabon monoxide gas is produced.

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.
