Answer:

4.22

Explanation:

According to the question, the pOH of the solution is 9.78. You may recall that pOH is the hydroxide concentration of a solution.

Also pOH = -log[OH^-]. Hence the pOH is obtained from the hydroxide ion concentration.

Finally, pH + pOH =14

Hence;

pH = 14-pOH

pH= 14-9.78 = 4.22

pH= 4.22

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.
