The needed mass is 35,549 g.
1.17 grams :)
You would need 18 grams to get the requirement. Using a chemical equation can help to solve this for you.
HCl has a molar mass of 36.461 grams per mole. This means that 72.922 grams of HCl are needed per liter of water to make a solution that has a concentration of 2M.
1.5 moles

Balanced equation first. 2Na + Cl2 -> 2NaCl 35 grams NaCl (1 mole NaCl/58.44 grams )( 1 mole Cl2/2 mole NaCl )( 70.9 grams Cl2/1 mole Cl2) = 21 grams of Cl2 needed
The answer is 6,71 g dried KCl.
600 mL of 0,9 % sodium chloride: 6 x 0,9 = 5,4 grams NaCl
5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.So the mass concentration = 5/80 = 100*5/80% = 6.25%5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.So the mass concentration = 5/80 = 100*5/80% = 6.25%5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.So the mass concentration = 5/80 = 100*5/80% = 6.25%5 grams of salt in 75 grams of water = 5 grams of salt in 80 grams of the solution.So the mass concentration = 5/80 = 100*5/80% = 6.25%
