1. Which of the following operators can you use in an EXCEL formula to help you calculate the 5th root of a number? @ $ 2. Which of these will calculate the number of atoms of hydrogen in 143 grams of methane? The molar mass of methane is in cell A3. O =(143/$A$3)*4*6.022e23 O=6.033e23/100*4*$A$3 O=143/$A$3*4*6.022e23 O =(143/$A$3)/4*6.022e23 O=143 6.022e23/4*$A$3 is a series of two or more adjacent cells in a column or row or rectangular group of cells. O SECTION O LIST O AREA ORANGE 3. A(n) O FORMULA 4. Cell C4 contains the formula B1 + B2. What formula will see if you copy the formula and paste it into cell J9? O = H5 + H6 O $16+ $17 O = G6 + G7 OB1 + B2 O = 16 + 17 5. When you copy a formula that contains an absolute reference to a new location, the reference O does not change O is updated automatically Obecomes bold O has a dotted outline in its cell

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
