a coal burning power station produces 70tonnes of sulpher dioxide in one day. what mass of sulphuric acid h2so4 is produced in the atmosphere if it reacts with oxygen and water as follows...
2so2+o2+2h2o forms 2h2so4 The answer is 107 tonnes but can someone show the workings.Thank you so much,I'm really struggling!

First thing you have to do is find the number of moles of SO2, since its Molar mass = 64, the numbe rof moles = 70,000,000/64
=1093750
Now the same number of moles of H2SO4 will be formed, and its Molar mass is = 98, so the total mass of H2SO4 formed will be = 1093750 x 98
=107187500g
=107tonnes

...Mol.Wt. SO2 = 32 + 32 = 64.
...70t ÷ 64mol/t = 1.09375 mol
...Mol.wt. H2SO4 = 2 + 32 + 64 = 98.
...1.09375 x 98 = 107.2t H2SO4 produced.

once you think of with reference to the traits contemporary in a real "soul mate" relationship, what one be conscious comes up maximum usually on the the suited option of your checklist? Is it Chemistry? probable. that's sometimes defined as a feeling that leaves you breathless, excited and susceptible interior the knees. palms sweat, the middle races and the physique tingles with worried anticipation. the tip maximum might-be enthusiasts come to is that in the event that they experience those severe emotions in direction of somebody, they have the foundation for an suited and lasting relationship. proper? perhaps no longer. For this definition of chemistry is constrained to one's actual reaction to a various individual. It lacks an entire length it somewhat is residing in our values, ideals, personalities and worldview. as a manner to renowned you have the the suited option connection with a ability (or contemporary) companion, it rather is significant to have a elementary information of what genuine chemistry contains, that encompass it. it somewhat is perplexing to do. This severe, actual hobby is the stuff that Oscar triumphing movies and suited-advertising books are made up of. So, take a step back for a minute and notice in case you recognize your self. :-)

The working is (70,000,000/64) x (98/1,000,000)
Now try and work out how I did it!

m[H2SO4]=[70t/(64kmol/t)]*(98kmol/t)=107.1875t
