Question

Дано:m(NHз)найти M(NHз)?​

Answer 1

Чтобы найти М(NH3) не нужно знать m. M(NH3) = M(N) + 3M(H) = 14+3 =17

Answer 2

Finding Molar Mass of \(NH_3\)

To find the molar mass (\(M(NH_3)\)) of \(NH_3\), we need to consider the molar masses of the individual elements in the compound.

The molar mass of \(N\) (nitrogen) is approximately 14.01 g/mol, and the molar mass of \(H\) (hydrogen) is approximately 1.008 g/mol.

Using this information, we can calculate the molar mass of \(NH_3\) as follows:

Molar mass of \(NH_3\): - \(N\) (nitrogen) has a molar mass of approximately 14.01 g/mol. - \(H\) (hydrogen) has a molar mass of approximately 1.008 g/mol.

Therefore, the molar mass of \(NH_3\) can be calculated as: \[ M(NH_3) = (1 \times 14.01) + (3 \times 1.008) \]

Let's calculate the molar mass of \(NH_3\).

Calculation

\[ M(NH_3) = (1 \times 14.01) + (3 \times 1.008) = 14.01 + 3.024 = 17.034 \, \text{g/mol} \]

Therefore, the molar mass of \(NH_3\) is approximately 17.034 g/mol.
