Final answer:
To produce a 0.150 M solution of NaCl in 500.0 g of water, you would need to dissolve 4.383 grams of NaCl.
Step-by-step explanation:
To calculate the number of grams of NaCl needed to produce a 0.150 M solution in 500.0 g of water, we first need to convert the concentration from moles per liter to moles per gram (since we have grams of water). Then, using the molar mass of NaCl, we can calculate the number of grams needed.
First, we calculate the number of moles of NaCl needed:
0.150 M NaCl x 0.500 L = 0.075 moles NaCl
Next, we convert moles to grams using the molar mass of NaCl:
0.075 moles NaCl x 58.44 grams/mole = 4.383 grams NaCl
Therefore, you would need to dissolve 4.383 grams of NaCl in 500.0 grams of water to produce a 0.150 M solution of NaCl.
