Chemistry
1 answer:
const2013 [10]3 years ago
5 0

Answer:

10.70grams

Explanation:

Density of a substance = mass/volume

At STP of a gas (standard temperature and pressure), the density of oxygen gas is 1.429 g/L

Hence, according to this question, in 7.49 L of oxygen gas, there would be:

Using D = m/V

1.429 = m/7.49

m = 1.429g/L × 7.49L

m = 10.70g

What is the total number of liters of SO3 produced when 32.0 of SO2 reacts completely
ahrayia [7]
Write  the   chemical  equation   for  reaction
that  is  
2SO2+O2  --->2SO2

find  the   moles  of  SO2   used  =  moles=mass/molar mass  of  so2

=  32g/80g/mol=0.4 moles

by  use  of  reacting  ratio  between  SO2   and  SO3   which   is   2:2  therefore  the  moles  of  so3  is  also =  0.4  moles

STP  1 mole  =  22.4L.
what  about  0.4moles

= 0.4 /1 x22.4=8.96 liters
