How many moles of aluminum do 6.3x1024 aluminum atom represent?
6.3x10^24 aluminum atoms represent 1 mole of aluminum atoms because Avogadro's number is approximately 6.022x10^23.
Molarity of a solution containing 0.456 grams CaCI in 250ml of solution?
First off we multiply .456 by 4 to get it into weight per litre. This gives us 1.824 grams per litre. Next, I'll assume you made a mistake here. Ca is 2+ so you need TWO chlorines (Cl-). I.e. the molecular weight is actually 111g/mol. 1.824/111 is 0.01643 molar. Be careful, because the wrong molecular weight can throw your answer off hugely, especially a heavy atom such as chlorine.

How many moles are in 76 grams of NaCl?
To calculate the number of moles in 76 grams of NaCl, you need to divide the given mass by the molar mass of NaCl. The molar mass of NaCl is approximately 58.5 g/mol. So, 76 grams of NaCl is equal to 76 g / 58.5 g/mol ≈ 1.30 moles.
What is the molarity of a solution prepare2.3 Ld by dissolving 456 g NaCL in?
Pretty concentrated! ( I assume you mean 2.3 Liters )First get the moles of sodium chloride.456 grams NaCl (1 mole NaCl/58.44 grams)= 7.803 moles NaCl==============Now,Molarity = moles of solute/Liters of solutionMolarity = 7.803 moles NaCl/2.3 Liters= 3.4 M NaCl solution----------------------------
