The chemical formula is determined by chemical analysis of the components.
By determining the molecular mass, then dividing the molecular mass by the formula mass of the empirical formula to determine by what integer the subscripts in the empirical formula must be multiplied to produce the molecular formula with the experimentally determined molecular mass.
Algebraic Steps / Dimensional Analysis Formula ____ lb*1 kg 2.2046 lb=? kg
To determine the density of a rubber eraser, you would first measure the mass of the eraser using a scale. Next, measure the volume of the eraser by submerging it in a graduated cylinder filled with water and recording the water displacement. Finally, divide the mass of the eraser by its volume to calculate the density.

15 inches equates to 38.1 cm Algebraic Steps / Dimensional Analysis Formula 15 in* 2.54 cm 1 in = 38.1 cm
The formula to calculate the rise and run of a staircase for deck steps is to divide the total height of the staircase by the desired number of steps to determine the rise, and then divide the total depth of the staircase by the number of steps to determine the run.

Completing the square is advantageous in several situations:usually, it requires fewer steps than the quadratic formula, reducing the potential for error.it allows you to determine the exact value of the answer instead of a decimal approximation.it allows you to determine imaginary solutions.
First you have to decide which program of study you are taking the doctorate in. Then you can determine the appropriate prerequisites.
