A gas is produced when 25 g of substance X is mixed into 60 g of solution Z in a beaker. The mass of the solution in the beaker
Zepler [3.9K]

mass of the gas = 10 g

<h3>Further explanation</h3>

<em>The law of conservation of mass :</em>

<em>In a closed / isolated system, the total mass of the substance before the reaction will be equal to the total mass of the reaction product.</em>

Reaction

\tt X+Z\rightarrow gas+solution

mass before reaction=mass after reaction

\tt 25+60=gas+75\\\\gas=25+60-75=10~g

What is the value that corresponds to the number of atom
chubhunter [2.5K]

Answer:

6.022 x 10²³

Explanation:

Data Given:

mass of carbon = 12.01 g

individual particles = 6.02 x 10²³

number of atoms = ?

Solution:

Formula used to find the number of atoms

                no. of moles = number of atoms / 6.022 x 10²³ . . . . . (1)

So, first we have to find number of moles

Formula to find no. of moles

               no. of moles = mass in grams/ molar mass. . . . . (2)

molar mass of Carbon = 12.01 g/mol

Put values in eq.2

            no. of moles = 12.01 g / 12.01 g/mol

            no. of moles = 1 mol

Now put the values in eq. 1

                no. of moles = number of atoms / 6.022 x 10²³ . . . . . (1)

                    1 mol = number of atoms / 6.022 x 10²³

Rearrange the above equation

               number of atoms = 1 mol x 6.022 x 10²³

                number of atoms = 6.022 x 10²³

So it is 6.022 x 10²³ atoms in 12.01 grams of carbon. This 6.022 x 10²³ also Known as Avogadro's number that is one mole of any substance consists this number of atoms.
