What is the total mass in grams of 0.75 mole of so2?

The total mass of 0.75 mole of SO2 is 48 grams.

Explanation:

To determine the total mass in grams of 0.75 moles of SO2, you must first determine the molar mass of the compound.  In order to determine the molar mass, you must know the atomic mass of each element that makes up the molecule. In this case, these masses are:

Since sulfur dioxide SO2 has 1 mole of sulfur S and 2 moles of oxygen O, the molar mass of the compound can be calculated as:

massmolarofSO2=32 g/mol+2*16 g/mol

massmolarofSO2=64 g/mol

Now, knowing the molar mass of the sulfur dioxide SO2, it is possible to determine the mass possessing 0.75 moles of the compound. This is done by a rule of three: if 1 mole of SO2 has a mass of 64 grams, how many grams are in 0.75 moles?

totalmass=48 grams

Finally, the total mass of 0.75 mole of SO2 is 48 grams.

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.
