Question

To make the following saline solution(375ml 0.5%w/v sodium chloride) what would you weight out?
what volume of water would you use?

Answer 1

0.5% NaCl w/v means 0.5 g NaCl in 100 mL solution. For 375 mL you will need
0.5 g NaCl x (375/100) = xx g NaCl. This assumes that adding 0.5 NaCl to 100 mL water will not increase the volume.
