Question

Si-0.1 мольN(Si)-?

Answer 1

Ответ: 6,02×10²²

Объяснение:

N=n×Na

Na=6,02×10²³

N=0,1×6,02×10²³= 6,02×10²²

Answer 2

To calculate the number of moles of nitrogen (N) in 0.1 moles of silicon (Si), we need to consider the molar ratio of nitrogen atoms to silicon atoms in the compound or substance.

The chemical formula of silicon nitride, which is a common compound containing both silicon and nitrogen, is Si3N4. In this compound, there are 3 silicon atoms and 4 nitrogen atoms.

Molar ratio of Si to N in Si3N4 = 3:4

Now, if we have 0.1 moles of silicon (Si), we can calculate the moles of nitrogen (N) as follows:

Number of moles of Si = 0.1 moles Molar ratio of Si to N = 3:4

Number of moles of N = (Number of moles of Si) * (Molar ratio of N to Si) Number of moles of N = 0.1 moles * (4/3) ≈ 0.133 moles

So, there are approximately 0.133 moles of nitrogen (N) in 0.1 moles of silicon (Si).
