Answer:

% age of hydrogen = 17.65%

Explanation:

Given data:

Mass of ammonia = 17.0 g

Mass of hydrogen = 3.0 g

Mass of nitrogen = 14.0 g

Percentage of hydrogen = ?

Solution:

Formula:

% age of hydrogen = mass of hydrogen / mass of ammonia × 100

Now we will put the values:

% age of hydrogen = 3.0 / 17.0 × 100

% age of hydrogen = 17.65%

For oxygen:

% age of hydrogen = mass of hydrogen / mass of ammonia × 100

Now we will put the values:

% age of hydrogen = 14/ 17.0 × 100

% age of hydrogen = 82.35%

Total percentage =  17.65% + 82.35%

Total percentage = 100%

PLEASE HELP Determine the number of neutrons for the given isotopes:
zepelin [54]
<span>Helium = 1
Carbon = 8
Nitrogen = 8
Strontium = 52
Tellurium = 71

If you look on a periodic table, on each element there is a number on the top left. This represents the number of protons in an atom. Protons have a mass of 1 (in relative to Carbon-13)

If we take nitrogen-15 for example; The number 15 tells you that the isotope has a mass of 15. Now if you look on the periodic table, Nitrogen has a proton number of 7. Only protons and neutrons have a mass, electrons are considered to be negligable. Therefore the number of neutrons Nitrogen-15 contains is 15 - 7 = 8 </span>
