The concentration of physiological saline is 0.9%. If you want to prepare 1000kg of physiological saline, the steps are: The first step: how many kilograms each salt and water are calculated. 1000kg*0.9%= 9kg (salt) 1000kg-9kg = 991kg (water) Step 2: Illects. Accurately call 9kg of salt and 991kg of water. The third step: dissolved. Put the salt into the water and stir it fully. After it is completely dissolved, it is 1000kg0.9%physiological saline.
