Shaw’s carries two types of apple juice. One is 100% fruit juice, while the other is only 40% juice. Yesterday there was only one 48-ounce bottle of the 100% juice left. I bought it, along with a 32-ounce bottle of the 40% juice. I am about to mix the contents of the two bottles together. What percent of the mixture will be actual fruit juice?

the percent of actual fruit juice in the mixture will be 76%

Explanation:

given that we are mixing 2 bottles the total volume the mixture will be

mixture volume = volume bottle 1 + volume bottle 2  = 48 ounces +  32 ounces = 80 ounces

also the total quantity of juice will be

juice mass in mixture = juice bottle 1  + juice bottle 2 = 48 ounces * 1 +  32 ounces * 0.4 = 60.8 ounces of juice

therefore the concentration of juice in the mixture will be

concentration = 60.8 ounces of juice / 80 ounces = 0.76 (76%)

therefore the percent of actual fruit juice in the mixture will be 76%

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.
