What Is The Mass Of $6.022 \times 10^{23}$ Formula Units Of $MgF_2$?
Introduction
In chemistry, understanding the mass of a substance is crucial for various calculations and applications. The mass of a substance can be calculated using its molar mass and the number of moles present. In this article, we will explore the mass of $6.022 \times 10^{23}$ formula units of $MgF_2$.
Understanding the Molar Mass of $MgF_2$
The molar mass of a substance is the mass of one mole of that substance. To calculate the molar mass of $MgF_2$, we need to find the atomic masses of magnesium (Mg) and fluorine (F). The atomic mass of Mg is approximately 24.305 g/mol, and the atomic mass of F is approximately 18.998 g/mol.
The molar mass of $MgF_2$ can be calculated by adding the atomic masses of Mg and two F atoms:
Molar mass of $MgF_2$ = atomic mass of Mg + 2 × atomic mass of F = 24.305 g/mol + 2 × 18.998 g/mol = 24.305 g/mol + 37.996 g/mol = 62.301 g/mol
Calculating the Mass of $6.022 \times 10^{23}$ Formula Units of $MgF_2$
To calculate the mass of $6.022 \times 10^{23}$ formula units of $MgF_2$, we need to use the Avogadro's number, which is $6.022 \times 10^{23}$ formula units per mole. We can calculate the mass of $MgF_2$ by multiplying the molar mass of $MgF_2$ by the number of moles present:
Number of moles = number of formula units / Avogadro's number = $6.022 \times 10^{23}$ formula units / $6.022 \times 10^{23}$ formula units/mol = 1 mole
Mass of $MgF_2$ = molar mass of $MgF_2$ × number of moles = 62.301 g/mol × 1 mole = 62.301 g
Conclusion
In conclusion, the mass of $6.022 \times 10^{23}$ formula units of $MgF_2$ is 62.301 g. This calculation demonstrates the importance of understanding the molar mass of a substance and using Avogadro's number to calculate the mass of a substance.
