What is the concentration of hcl in the final solution when 65 ml of a 9.0 m hcl solution is diluted with pure water to a total volume of 0.15 l?

"the periodic table is arranged in order of atomic number."

the answer is na (sodium)

50.23 i believe is correct but don't quote me on that.

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but
