Please help ASAP! What would this coefficient be 2S02(g) + O2(g) --> ?S03(g)

The coefficient of SO3 is 2

Explanation:

2SO2(g) + O2(g) —> ?SO3(g)

To know the coefficient of SO3 in the equation above, we must first balance the equation.

The equation can be balance as illustrated below:

2SO2(g) + O2(g) —> SO3(g)

There are 2 atoms of S on the left side and 1 atom on the right side. It can be balance by putting 2 in front of SO3 as shown below:

2SO2(g) + O2(g) —> 2SO3(g)

Now, we can see that the equation is balanced. Thus, the coefficient of SO3 is 2.

thats how its supposed to be

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
