The answer cannot be known without knowing the substance you are talking about. Kilograms is weight, and cubic yards is volume. A cubic yard of gold is going to weigh more kilograms than a cubic yard of hay.
Net weight is the weight of the contents of a package only, and is rarely used in shipping.Gross weight is the total weight of the package, including the contents plus any wrapping, boxing or pallet. It is this weight (or alternatively, dimensional weight) that determines the cost of shipping.
Being pH balanced means that the substance has a neutral pH of 7. This means that there are equal amounts and strengths of acidic and basic substances.
Just remember the fact that "gross" is german (and also french) for "large" therefore gross is "larger" than net. so in the case of income for example...your gross income is "larger" than your net income (i.e. gross income is before tax). in the case of a can of food, gross weight is "larger" than net weight (i.e. gross is weight of the food+tin+water...net weight is weight of just the food).

The weight will depend on how much of the substance there is.

Not completely. The empirical formula of a substance can be determined from its percent composition, but a determination of molecular weight is needed to decide which multiple of the empirical formula represents the molecular formula.
It is the French term for "net weight", which is the weight of a substance, not including the weight of the container it's in; "gross weight" includes the weight of the substance and the container.
That depends not on the given concentration percentage (18%) but solely on the quantity (amount) of HCl (or any other) substance!
