Molarity (M) = (moles of solute) ÷ (liters of solution). To calculate the number of moles of a solute, you need two pieces of information, which you may have to infer from other data. The first is the chemical formula of the solute, and the second is the mass of the solute. Yo...
Calculate the amount of the component in moles using the formula, Amount (in moles) =mass (compound)/molecular mass (compound). In our example, Amount (NaOH)=0.5 g /40 g/mole= 0.0125 moles. Step 3 Convert moles to millimolesusing the following proportion: 1 mole corresponds to 1 milli...
To calculate the force of impact, divide kinetic energy by distance. Impact and Energy Impact and Energy Energy is defined as the ability to do work. During an impact, an object's energy is converted into work. The energy of a moving object is called kinetic energy, and is equal to one...
If you see "normal" as "expected," even in the chemical sense this is more or less on target: A normalized preparation is one that has been created in proportion or relation to an established standard. To discover how to calculate the normality of NaOH, or how to convert from normality ...
Find the molarity of a solution that is made by dissolving 76.54g NaCl in enough water to make a 3,567 mL solution. Calculate the pH of a buffer solution prepared from 0.155 mol of phosphoric acid, 0.250 mol of KH_2PO_4, and enoug...
Molecular Weight Input Value From To Calculate Mass from Molarity Calculate the required mass of compound in a specific volume of solvent to achieve the target molarity (molar concentration). Molecular Weight Volume Molarity Volume Unit Converter Use calculator to convert mass units Volume From To Mas...

Calculate the mean of the squared differences.(4+25+4+9+25+0+1+16+4+16+0+9+25+4+9+9+4+1+4+9) / 20 = 178/20 = 8.9 This value is the variance. The variance is 8.9 The population standard deviation is the square root of the variance. Use a calculator to obtain this number...
First, you need to know how a scientific calculator is different from other calculators. There are three main types of calculators: basic, business, and scientific. You can't workchemistry, physics, engineering, or trigonometry problems on a basic or business calculator because they don't have ...
