✅ Issues with interfaces and generic classes

public class Mol<IAmount>
{
    public double Amount { get; set; }
    public required IAmount Compound { get; set; }

    public static Mol<IAmount> Of(IAmount compound, double amount)
    {
        return new Mol<IAmount>() { Amount = amount, Compound = compound };
    }
}

    public static Solution Of(Mol<ISolute> solute, Volume<ISolvent> solvent)
    {
        return new Solution() { Solute = solute, Solvent = solvent };
    }
