If a plant produces 9.31 mol of c6h12o6, how many moles of h2o are needed?

Answer;

55.86 moles

Explanation;

Six molecule of H2O is needed for every molecule of C6H12O6 to be produced.

This means the ratio of H2O: C6H12O6 is 6:1  

Let H2O mole= X  

Therefore...

X/9.31 = 6/1  

X= 6 x 9.31

X = 55.86 moles

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
