CO2, C2H2, BeF2, XeF2, etc all these molecules have linear geometry.
When two atoms combine, the overlap of their atomic orbitals produces molecular orbitals.
Answer:
mass of Helium = mole of Helium x Molarmass of Helium
Explanation:
Mole of Helium = volume of Helium/ 22.4dm^3/mol
= 7.00 x 10^2/22.4
= 31.25mol
Mass of Helium = mole of Helium x Molarmass of Helium
= 31.25mol x 4g/mol
= 125g
The answer is Nitrogen monoxide
