How many grams of nacl are in 500 ml of 1/2 ns? (answer must be numeric; no units or commas; include a leading zero when answer is less than

To determine how many grams of sodium chloride is present in the given volume of an NS solution, we need to understand first what is an NS solution. NS stands for normal saline solution. This solution would have a concentration of 0.90% by w/v of NaCl salt or 9.0 grams per liter solution. To determine the mass of the salt, we simply multiply the volume of the solution to the concetration of the NS solution. We do as follows:

mass NaCl = 500 mL ( 1 L / 1000 mL ) ( 9.0 grams / L) ( 1/2) = 2.25 grams

Therefore, 500 mL of 1/2 NS solution has about 2 g of NaCl.
