A solution is prepared by dissolving 7.14 g KClO in 318 g of water. What is the molality of this solution? You do not need to show work!

im not that sure but i think 2.7132

Explanation:

change the 7.14g to litres and change 318g to litres

then use 7.14/318 ( after changing the numbers )

the answer would be a

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
