Question

The molarity of 98% H2SO4 d =1.8 g/ml by wt

Answer 1

Answer:

Approx. 18⋅mol⋅L−1....

Explanation:

Now this is concentrated sulfuric acid...and to find its molarity we interrogate the quotient....

Moles of sulfuric acidVolume of solution

And we can assess its concentration by taking a 1⋅mL volume and thus....

98%×1.80⋅g98.08⋅g⋅mol−11×10−3⋅L=??⋅mol⋅L−1.....

Of course this is consistent dimensionally, in that 1mol−1=11mol=mol as required.........
