Question

no. Of moles of nitrogen atom in 56g nitrogen gas

Answer 1

hi friends

mass of nitrogen gas = 56g
molecular mass of nitrogen = 14

number of moles = mass/ molecular mass.
= 56/14
= 4 moles
there are 4 moles of the nitrogen atom in 56g nitrogen gas.

thank you

Answer 2

4 moles of the nitrogen atom in 56g nitrogen gas.

How do you calculate the number of moles of nitrogen gas?

• The molar mass (M) of N2 is 28.014 g/mol.
• n = m/M, where n = moles, m = mass in grams, and M = molar mass in g/mol.
• Since M is a fraction, you can divide by multiplying by its reciprocal.
• n = 1 g N2 × (1 mol N2/28.014 g N2) = 0.04 mol N2 to one significant figure.

How many atoms are in nitrogen gas?

• Molecular nitrogen (N2) is a very common chemical compound in which two nitrogen atoms are tightly bound together.
• Molecular nitrogen is a colorless, odorless, tasteless, and inert gas at normal temperatures and pressures.

How do I calculate moles?

The unit is denoted by mol:

• The formula for the number of moles formula is expressed as Given.
• Number of moles formula is.
• Number of moles = Mass of substance / Mass of one mole.
• Number of moles = 95 / 86.94.

According to the question:

mass of nitrogen gas = 56g.

molecular mass of nitrogen = 14.

number of moles = mass/ molecular mass.

= 56/14.

= 4 moles.

Hence, there are 4 moles of the nitrogen atom in 56g nitrogen gas.
