Given the mass of =25.6 g

The molar mass of =390.35g/mol

Conversion of mass of to moles:

Conversion of moles to moles of sulfur:

Conversion of moles of sulfur to individual sulfur atoms using Avogadro's number:

1 mol =

Laws of Nature should be differentiated from Scientific and Natural Laws. The Necessitarian Theory suggests that Laws of Nature are those principles which influence the natural phenomena in the universe, meaning the natural world adheres to them.

Given parameters:

Mass of sucrose  = 5g

Density of sucrose  = 1.12g/mL

Percentage of sucrose per liter of cane juice  = 12%

Unknown:

Volume of cane juice required =?

We need to understand the relationship between volume and density. Density represents mass per unit volume.

Mathematically;

                Density  =

Now, calculate the volume of sucrose;

                  1.12g/mL =

       Volume  =    =  4.46mL   = 4.46 x 10⁻³L since 1000mL  = 1L

Since 12% of one liter of cane juice is sucrose,  

                    12% of  x  liter of cane juice  = 4.46 x 10⁻³L

                   Volume of cane juice  = 4.46 x 10⁻³ x   = 0.037L

Volume of cane juice needed is  0.037L

   

It must be a physical change unless a chemical substance interacts with the metal surface, resulting in a chemical change.
