Answer:
You take the atomic, or proton number of the element, and you subtract it from the element's mass number.
Answer : The percentage composition of carbon, hydrogen and sulfur in a compound is, 38.8 %, 9.6 % and 51.6 % respectively.
Explanation :
To calculate the percentage composition of element in sample, we use the equation:

Given:
Mass of carbon = 1.94 g
Mass of hydrogen = 0.48 g
Mass of sulfur = 2.58 g
First we have to calculate the mass of sample.
Mass of sample = Mass of carbon + Mass of hydrogen + Mass of sulfur
Mass of sample = 1.94 + 0.48 + 2.58 = 5.0 g
Now we have to calculate the percentage composition of a compound.



Hence, the percentage composition of carbon, hydrogen and sulfur in a compound is, 38.8 %, 9.6 % and 51.6 % respectively.
Answer: 2800 g
Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number
of particles.
Given mass = 5 kg = 5000 g
1 mole of
produces = 1 mole of 
50 moles of
produces =
of 
Mass of 
2800 g of
is produced from 5.0 kg of limestone.
