This phrase (not a complete sentence or even a question) is so poorly worded, I can only guess at the answer of relative cell address.
It contains relative cell references.
if you move or copy the formula to another cell, the cells referred formula will changed. Excel adjusts the cell references relative to the new cell in which the formula is pasted. this is called relative referencing.
To reference a cell relative to the one containing the formula, you can use relative cell references. For example, if the formula is in cell A1 and you want to reference the cell one column to the right, you can use B1. If you want to reference the cell one row down, you can use A2. This way, the reference adjusts based on the formula's location.
No. It contains relative references only.
A formula unit can also be referred to a mole unit. A mole or formula unit is the smallest amount of a substance that contains all the atoms or elements of a substance.
The elements a compound contains and the exact number of atoms of each element in one unit of that compound is referred to as the chemical formula of the compound.
When cell C3 containing the formula B6C8 is copied to cell D2, the formula in D2 will adjust based on its new location. It will become C6D8, as Excel automatically updates the cell references relative to the position of the new cell. This is known as relative referencing.
The relative addresses will change as the formula is copied.
