Final answer:
To create a cell reference in a formula, click the cell where you want to include the cell reference. This is typically used in spreadsheet applications like Excel, where you may be calculating the molecular or formula mass of a compound by referring to cells containing quantities and atomic masses.
Step-by-step explanation:
To create a cell reference in a formula, you can simply type in the cell name or you have the following options: A. Clicking the cell, B. right-clicking the cell, C. clicking the row where the cell is located, D. clicking the column where the cell is located. The correct answer is A. Clicking the cell. This action will add the cell reference to your formula, making it easy to include the values from that specific cell in your calculations.
Example of creating a cell reference
Let us consider you have an Excel table where you are calculating the molecular mass or formula mass of a compound. Assume the table has various elements and their average atomic mass listed, along with the quantity of each present in the compound. To calculate the subtotal atomic mass (a m u) for each element, you would click on a cell where you want to display the subtotal, start your formula with an equals sign '=', then click on the cell containing the quantity of that element, type a multiplication sign '*', and finally click on the cell containing the average atomic mass. The subtotal for each element will then be calculated automatically.
