Answer:
4.5moles
Explanation:
2.25moles times 2 hydrogen atoms per one molecule
The number of hydrogen atoms present in 2.25 moles of hydrogen carbonate is 4.5.
What is a mole?
A mole of a compound is equivalent to the one formula unit of the compound. The number of atoms of each element in a mole of the compound can be given from the formula unit.
1 unit of hydrogen carbonate consists of 2 atoms of hydrogen. Thus, 1 mole of hydrogen carbonate has 2 hydrogen atoms.
The number of hydrogen atoms in 2.25 mole of hydrogen carbonate can be given as:
[tex]\rm 1\;mol\;H_2CO_3=2\;atoms\;Hydrogen\\2.25\;mol\;H_2CO_3=2.25\;\times\;2\;atoms\;of\;hydrogen\\2.25\;mol\;H_2CO_3=4.5\;atoms \;of\;Hydrogen[/tex]
