Overview Page 2 this is row 1 (rows are represented by numbers 1, 2, 3 ...) Spreadsheet programs are pages divided as rows or columns this is column A (columns are represented by letters A, B, C ...) The rows and columns intersect to define a cell this is a cell (cell D12) The cells in a spreadsheet program can contain: numbers 1, 2.5, 99.6 e-3 text this is a line of text that extends past the end of the cell formula "= D8 * C7" <- this formula means take the contents of cell D8 and multiply it by the contents of cell C7 and put the result here When you type in a formula, do not type the quotation marks. Example 8.45E-15 <- cell D28 9.56 <- cell D29 0 <- cell D28 times cell D29 (the formula is = D28*D29) When you change a value in a cell, all of the values that rely on that cell are automatically recalculated to reflect the new value. If you add new cells in between, the cell references change automatically. You can define a cell reference to be a specific one by using \$ signs "=\$D\$5" use the value in cell D5 and do not change this as the refere A B C D E F G H I 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41

They will be calculated when you type ente Example Calculation of Molar Masses Step 1 Enter compound in one cell and formula in a block of cells as shown A B C D E F G H 1 Compound 2 H2SO4 H 2 1.01 3 S 1 32.06 4 O 4 16 Step 2 Now define cell E2 with the formula "=c2*d2"

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
