What volume, in liters, would 88.9 grams of a substance occupy if it’s density is 2.38 g/mL

V = 0.03735 mL

Explanation:

Given that,

Mass of a substance, m = 88.9 grams

Density of a substance, d = 2.38 g/mL

We need to find the volume occupied by the object. The density of an object is given by mass per unit volume.

So, the volume of the substance is 0.03735 mL.

h let me think

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.
