What is the percent composition of hydrogen in a compound if the mass of the initial compound is 276 gram and the mass of collected hydrogen after decomposition is 41.4 grams?

The percentage composition of hydrogen in the given compound is 15%.

Explanation:

To calculate the percentage composition of hydrogen in a compound, we use the formula:

Where,

Mass of hydrogen = 41.4 grams

Mass of compound = 276 grams

Putting values in above equation, we get:

Percentage composition of hydrogen in a given compound = 15%

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d

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.
