Answer:
2.47 M
Explanation:
Molarity is (mol of solute)/(L of solvent). To find molarity, convert grams of NaCl to moles of NaCl and milliliters of water to liters of water.
72.3 g ÷ 58.44 g/mol = 1.2372... mol
500 mL ÷ 1000 mL = 0.5 L
Molarity = 1.2372/0.5 = 2.47 M
The two samples don’t contain different atoms so it will be false
The chemicals combination of the atoms is called a compound. The bond is formed between the atoms of each of the reacting elements thereby forming a new substance altogether. The compound will often exhibit different characteristics from the originating elements.
