要计算给定物质的质量中所含的摩尔数，首先需要知道该物质的摩尔质量。摩尔质量是物质的相对分子质量，单位为克/摩尔（g/mol）。以水（H₂O）为例，其摩尔质量为18.015 g/mol（2×1.008 g/mol for hydrogen + 15.999 g/mol for oxygen）。使用摩尔质量，可以通过以下公式计算物质中含有的...
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...
Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles. When dividing by two units that both use grams in their measurement ...
