What is the molarity of a solution of hf if 4.400 moles of hf are added to a container and filled with water to a final volume of 6.00 l?

Answer is: the molarity of a solution of HF is 0.73 M.

n(HF) = 4.400 mol; amount of hydrofluoric acid.

V(HF) = 6.00 l; volume of hydrofluoric acid.

c(HF) = n(HF) ÷ V(HF).

c(HF) = 4.400 mol ÷ 6.00 l.

c(HF) = 0.733 mol/l; molarity of a solution (hydrofluoric acid).

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
