We need to measure 20.0 grams of CaCl₂ to prepare 500 mL of 0.360 M solution.
First, we need to determine the required moles of CaCl₂. We have 500 mL (0.500 L) of a 0.360 M solution (0.360 moles of CaCl₂ per liter of solution).
Then, we will convert 0.180 moles to grams using the molar mass of CaCl₂ (110.98 g/mol).
To prepare the solution, we weigh 20.0 g of CaCl₂ and add it to a beaker with enough distilled water to dissolve it. We stir it, heat it if necessary, and when we have a solution, we transfer it to a 500 mL flask and complete it to the mark with distilled water.

<h3>How are units labeled?</h3>
Use standardized unit abbreviations. For clarity, place units of before nonstandard units, such as (a) (units of a). When separating the components of a compound unit, use short spaces rather than hyphens, dots, or other symbols. For numbers on figure axes, use superscripts, multiplication signs, and powers of 10.
<h3>What is label in math means?</h3>
A graph labelling is the process of assigning labels, which are typically represented by integers, to the edges and/or vertices of a graph in the field of mathematics known as graph theory.
