6.8: Calculating Empirical Formulas for Compounds
Determining Empirical Formulas. An empirical formula tells us the relative ratios of different atoms in a compound. The ratios hold true on the molar level as well. Thus, H 2 O is composed of two atoms of hydrogen and 1 atom of oxygen. Likewise, 1.0 mole of H 2 O is composed of 2.0 moles of hydrogen and 1.0 mole of oxygen.We can also work backwards …

characterized as sodium feldspar. The Hardgrove grindability test used a ball-race test mill. The Hardgrove grindability indices of these feldspar samples had an average of 46.25. Knowing the average Hardgrove index, a calculated work index of 12.88 kW/STPH was estimated using Aplan's empirical formula.

9.3: Double-Angle, Half-Angle, and Reduction Formulas
These formulas are especially important in higher-level math courses, calculus in particular. Also called the power-reducing formulas, three identities are included and are easily derived from the double-angle formulas. We can use two of the three double-angle formulas for cosine to derive the reduction formulas for sine and cosine.
Adiabatic Index: Definition, Formula, Examples & Applications
The adiabatic index is related to specific heat capacities (CP and CV ) through the equation γ= CP /CV. The difference between the specific heat capacities arises from the work done against external pressure during expansion or compression. The nature of gases contributes to CP being greater than CV, resulting in γ>1.
Refractive Index Formula
So, when light travels from vacuum to a medium, two angles are formed, i.e., angle of incidence(i) and angle of refraction(r), and the formula for refractive index is given by: n = [frac{sin i}{sin r}] (Image will be Uploaded Soon) There are two types of refractive index formula, and they are: Absolute Refractive Index. Relative Refractive Index
Cardiac Output and Cardiac Index – What's the Difference?
Cardiac Output Formula Cardiac output (CO) is the volume of blood the heart pumps per minute. Cardiac output is calculated by multiplying the stroke volume by the heart rate. Stroke volume is determined by preload, contractility, and afterload. The normal range for cardiac output is about 4 to 8 L/min, but it can vary depending on the body's ...

VLOOKUP and INDEX-MATCH Examples in Excel
INDEX-MATCH Example. Next, you'll see that the INDEX-MATCH formula is just as simple: = INDEX (result_range, MATCH (lookup_value, lookup_range,0)) How it works: The MATCH function returns the position number 3 because "a_003" matches the 3rd row in the Item ID range. Next, INDEX(result_range,3) returns the 3rd value in the price list range.The INDEX …
