Answer:
1.56 × 10²⁴
Step-by-step explanation:
In 1 mole of C₆H₁₄O there are 14 moles of atoms of hydrogen. In 0.185 moles of C₆H₁₄O, the moles of atoms of hydrogen are:
0.185 mol C₆H₁₄O × (14 mol H/1 mol C₆H₁₄O) = 2.59 mol H
In 1 mole of atoms of hydrogen, there are 6.02 × 10²³ atoms of hydrogen (Avogadr's number). In 2.59 moles of atoms of hydrogen, the number of atoms of hydrogen is:
2.59 mol H × (6.02 × 10²³ atoms H/ 1 mol H) = 1.56 × 10²⁴ atoms H
There are 1.56 × 10²⁴ atoms of hydrogen.
