Can anyone help me with this?

(a)

--- Silicon

--- Tin

-- Lead

(b)

--- Silicon

--- Tin

--- Lead

Explanation:

Given

The attached table

Solving (a): The volume of each sample

For each element, the volume (v) is calculated as:

Where:

So, we have:

Silicon:

So, we have:

Tin:

So, we have:

Lead:

So, we have:

Solving (b): The density of each sample

For each element, the density (d) is calculated as:

Where

So, we have:

Silicon:

--- calculated in (a)

Density (d):

Tin:

--- calculated in (a)

Density (d):

Lead:

--- calculated in (a)

Density (d):

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
