Answer:moles = no. of molecules / Avogadro's number
= 2.26 x 10^33 / 6.022 x 10^23
= 3752906011
Round to significant figures which is 3 = 3.75 x 10^9 mol
Explanation:
The formula for finding how many moles of a substance when given the amount of molecules is: moles = number of molecules / Avogadro's number
There are 3.75 × [tex]10^9[/tex] moles of sulfur dioxide are present in 2.26 × [tex]10^3^3[/tex] sulfur dioxide molecules.
The formula for calculating the number of moles is as follows:
The Number of moles = Number of molecules × Avagadro number.
Number of molecules = 2.26 x [tex]10^3^3[/tex]
Avogadro number = 6.023 × [tex]10^2^3[/tex]
∴ The number of moles = 2.26 × [tex]10^3^3[/tex] × 6.023 × [tex]10^2^3[/tex] = 3752906011 moles.
Now convert in number into power form, it will equal to:
3.75 x [tex]10^9[/tex] moles.
Once again, the formula for estimating the number of moles of a substance when the number of molecules is specifically given in the question is calculated by:
The Number of moles = Number of molecules × Avagadro number.
Therefore, there are 3.75 × [tex]10^9[/tex] moles of sulfur dioxide present in 2.26 × [tex]10^3^3[/tex] sulfur dioxide molecules.
