What is the percent composition of hydrogen in a compound if the mass of the initial compound is 276 gram and the mass of collec
mariarad [96]

Answer: 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:

\%\text{ composition of hydrogen}=\frac{\text{Mass of hydrogen}}{\text{Mass of compound}}\times 100

Where,

Mass of hydrogen = 41.4 grams

Mass of compound = 276 grams

Putting values in above equation, we get:

\%\text{ composition of hydrogen}=\frac{41.4g}{276}{\times 100

Percentage composition of hydrogen in a given compound = 15%

Elza [17]

Answer:

As previously discussed, there is a connection between the number of protons in an element, the atomic number that distinguishes one element from another, and the number of electrons it has. In all electrically-neutral atoms, the number of electrons is the same as the number of protons. Each element, when electrically neutral, has a number of electrons equal to its atomic number.
