Calculate the amount of moles in 6.75 liters of nitrogen gas.
tia_tia [17]

Answer:

There are 0.301 moles of N2 gas in 6.75 liters of N2 gas.

Explanation:

Given,

Volume of N2 gas = 6.75 L

We know,

At STP,

Number of moles = \frac{Volume}{22.4 L}   [Here 22.4 liter is the molar volume of any gas at STP]

                              = \frac{6.75L}{22.4L}

                              = 0.301

∴There are 0.301 moles of N2 gas in 6.75 liters of N2 gas.

Why does oxygen have a melting point
Jlenok [28]

Answer:

The intermolecular forces between water molecules are stronger than those between oxygen molecules. In general, the bigger the molecule, the stronger the intermolecular forces, so the higher the melting and boiling points.
