How many atoms are in the mole of magnesium
Pani-rosa [81]

Answer:

6.02 × 10²³ atoms.

Explanation:

According to the Avogadro number, the one mole of any substance have 6.02 × 10²³ atoms.

The number 6.02 × 10²³ is called Avogadro number. it is the number of atoms, ions or molecules in one gram atoms of element, one gram ions of substance or one gram molecules of a compound.

For one mole of magnesium.

24.305 g of Mg = 1 mole of magnesium =  6.02 × 10²³ atoms of magnesium.

Other example includes:

18 g of water = one mole of water =  6.02 × 10²³ molecules of water.

23 g of sodium = one mole of sodium =  6.02 × 10²³ atoms of sodium.

Draw the structure for 1-nitrobutane, making sure to add all non-zero formal charges.
TiliK225 [7]

The molecular structure of 1-nitrobutane is C_{4} H_{9} NO_{2}. The structure of 1-nitrobutane is shown below.

An atom's formal charge would be determined by the covalent model of chemical bonding, which assumes that almost all chemical bonds include equal sharing of electrons among all atoms, regardless their relative electronegativity.

The structure for 1-nitrobutane, making sure to add all non-zero formal charges

There are four kind of molecule present in 1-nitrobutane and they are carbon, hydrogen , nitrogen and oxygen. Nitrogen is bonded with two oxygen atom out of them one oxygen atom is attached with single bond and second oxygen atom is bonded with double bond. Nitrogen has positive charge whereas oxygen has negative charge.

It is a kind of alkane in with nitro group is attached with alkane group.
