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 find the molar mass of a compound, you need to add the molar mass of all the elements in that compound. Take a look at NaOH which contains sodium, oxygen and hydrogen. The molar mass of sodium is 22.99 g/mol, oxygen is 15.999 g/mol, and hydrogen is 1.008 g/mol. Adding them t...
Calculate the molarity of a 5% glucose solution. How many grams of glucose (C6H2O6 molecular mass=180 daltons) would be present in one liter of a 1M (molar) solution of glucose? To prepare a 248 mM sugar solution, how many sugars (molecular weight = 309 g/mol...
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...
