How much mass do 2.6 moles of gold contain

512.114 g

Explanation:

We are given;

Number of moles of gold as 2.6 moles

we are required to calculate the mass of gold

To answer the question, we need to understand the relationship between mass, molar mass and moles.To calculate number of moles of an element we divide mass of the element by its molar mass.That is; Moles = Mass ÷ molar massRearranging the formula;

Mass = Moles × molar mass

In this case;

Molar mass of Gold is 196.967 g/molTherefore;

Mass of Gold = 2.6 moles × 196.967 g/mol

                      = 512.1142 g

                      = 512.114 g

Thus, the mass of gold is 512.114 g

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
