Question

Молекулярная масса NH4OH

Answer 1

Mr(NH2OH)=14+1*2+16+1=33

Answer 2

To calculate the molecular mass of NH4OH, you need to add up the atomic masses of all the atoms in the formula.

The formula for NH4OH can be broken down as follows:

• NH4: Ammonium ion (NH4+) consists of one nitrogen atom (N) and four hydrogen atoms (H).
• OH: Hydroxide ion (OH-) consists of one oxygen atom (O) and one hydrogen atom (H).

Now, let's find the atomic masses of each element:

• N (Nitrogen) atomic mass ≈ 14.01 g/mol
• H (Hydrogen) atomic mass ≈ 1.01 g/mol
• O (Oxygen) atomic mass ≈ 16.00 g/mol

Now, calculate the molecular mass of NH4OH:

Molecular mass = (Number of N atoms * atomic mass of N) + (Number of H atoms * atomic mass of H) + (Number of O atoms * atomic mass of O)

Molecular mass = (1 * 14.01) + (4 * 1.01) + (1 * 16.00) ≈ 14.01 + 4.04 + 16.00 ≈ 34.05 g/mol

Therefore, the molecular mass of NH4OH is approximately 34.05 g/mol.
