You want to make 1M solution of NaCl. How much NaCl would you weigh out to add to 500ml of water?
Answer:
To make a 1M solution of NaCl using 500ml of water, you would need to weigh out 29.22 grams of NaCl.
Explanation:
To make a 1M solution of NaCl, we need to know the molar mass of NaCl, which is 58.44 g/mol. A 1M solution means that there is 1 mole of NaCl dissolved in 1 liter of water. In order to make a 1M NaCl solution using 500ml of water, we need to calculate the mass of NaCl needed.
Moles of NaCl = 1M x 0.5 L = 0.5 moles
Mass of NaCl = Moles x Molar mass
= 0.5 moles x 58.44 g/mol
= 29.22 grams
