There are different strains of the flu virus every year. The flu causes a fever, body aches, a headache, a dry cough, and a sore or dry throat.
Best Answer: But if you're lucky, you're talking about water, where the density is 1 g/mL, so there is 1 Kg in a Liter, and 1000 mL/L, and...
Dissolving this 37.25 g of KCl in a litre of water would give a 0.5 M solution. If 1 L or 1000 mL of 0.5 M solution contains 0.5 moles then 1 mL of the same concentration solution would contain 0.5/1000 moles and 250 mL would contain 250 x 0.5/1000 moles = 0.125 moles.0.125 moles of KCl is 0.125 mol x 74.5 g/mol = 9.31 g.2 people found this useful.olar mass of KCl = 39 g/mol (K) + 35.5 g/mol (Cl) = 74.5 g/mol. A 0.5 M solution is required (0.5 mol/L or 0.5 moles per litre). 0.5 moles of KCl is 0.5 mol x 74.5 g/mol = 37 â¦ .25 g.
