Calculate the mass, in grams, of a single xenon atom (mxe = 131.29 amu ).

Mariana [72]

Answer is $2.18017\times10^{-22}gms$ .

Explanation: To calculate the mass of 1 Xe-atom , we will require atomic mass of Xe which is 131.29amu.

This atomic mass is the mass of 1 mole of 1 Xe-atom. One mole of Xe-atom is $6.022\times10^{23}$ atoms of Xe. We will use this relation to convert Mass of Xe-atom into grams.

$\frac{\text{mass of 1 atom}}{atom}=\frac{\text{mass of 1 mole of atom}}{6.022\times10^{23}atoms}$

$\text{mass of 1 atom}=\frac{\text{mass of 1 mole of atom}}{6.022\times10^{23}}$

$\text{mass of 1 Xe-atom}=\frac{131.29}{6.022\times10^{23}}$

$\text{mass of 1-Xe atom}=21.8017\times10^{-23}gms$

= $2.18017\times10^{-22}gms$

Explain what the horizontal and vertical lines of a Fischer Projection indicate about the structure of the molecule

gulaghasi [49]

Explanation:

Fischer Projections allow to represent the three dimensional molecular structures in two dimensional environment without the change in the properties or the structural integrity of the compound. <u>It consists of horizontal as well as vertical lines both, where horizontal lines represent atoms which are pointed toward viewer while vertical line represents atoms which are pointed away from viewer. </u>The point of the intersection between horizontal and vertical lines represents central carbon.
