Explanation:
Hello!
In this case, since we can see that the heat released by the combustion of the mayonnaise is absorbed by the bomb calorimeter and water, we can set up the following equation:
Whereas q for mayonnaise stands for the heat due to its usage; thus, we plug in to obtain:
Now, if 10.0 g are eaten, the energy provided by it turns out:
And we need that value in dietary calories, 1 kcal:

Answer:
1.22 × 10^22 H atoms
Explanation:
From this question, TNT has the chemical formula: C-H5N306. The number of nitrogen atoms in the TNT substance is said to be 7.30 × 10^21 atoms.
The number of hydrogen atoms in the same TNT substance can be got using mole ratio. Based on the chemical formula, the mole ratio of hydrogen to nitrogen is 5:3 i.e. H5N3.
This means that;
Number of atoms of hydrogen = 5/3 of the number of atoms of nitrogen.
Hence, number of H atoms = 5/3 × 7.30 × 10^21
number of H atoms = (7.30 × 5/3) × 10^21
number of H atoms = (36.5/3) × 10^21
number of H atoms = 12.1666 × 10^21
number of H atoms = 1.2166 × 10^22 atoms.
Approximately, number of H atoms in TNT is 1.22 × 10^22 atoms.
