Answer:
6
Explanation:
The number of hydrogen atoms in the given compound is 6 atoms.
Given compound is:
3H₂CO₃
An atom is the smallest indivisible particles of an element.
In the compound;
3H₂CO₃
Elements Number of atoms
H 3(2) = 6
C 3(1) = 3
O 3(3) = 9
The number of hydrogen atoms in the compound is 6
In the dark waters just below the photic zone, because of cellular respiration, the concentration of dissolved carbon dioxide is higher relative to dissolved oxygen.
In cellular respiration living organisms use oxygen and release carbon dioxide, because there is little or no light there is no photosynthesis and oxygen is little produced.
MA= output force/input force
MA= 100N/20N
MA= 50
Answer: The mass percent of hydrogen in ascorbic acid is 4.5 %
Explanation:
In 
, there are 6 carbon atoms, 8 hydrogen atoms and 6 oxygen atoms.
To calculate the mass percent of element in a given compound, we use the formula:
Mass of hydrogen = 
Molar Mass of ascorbic acid =
Putting values in above equation, we get:
Hence, the mass percent of of hydrogen in ascorbic acid is 4.5 %.
