Question: how many hydrogen atoms are contained in 1.50 gram of glucose?
Answer: Hence the number of moles of hydrogen = (12 × 1.50) ÷ 180 mol = 0.10mol. Therefore, the total number of hydrogen atoms can be known by multiplying this mentioned value by the Avogadro Constant which is 6.02 × 10²³. So the answer is 6.02 × 10²² atoms of hydrogen are contained in 1.50 gram of glucose.
