How many grams are there in 2.00 moles of sulfuric acid

196g

Explanation:

We'll begin by obtaining the molar mass of sulphuric acid as shown below:

Molar Mass of sulphuric acid(H2SO4) = (2x1) + 32 + (16x4) = 2 + 32 + 64 = 98g/mol

Number of mole of H2SO4 = 2 moles

Mass of H2SO4 =?

Mass = number of mole x molar Mass

Mass of H2SO4 = 2 x 98 = 196g

Therefore, 2moles of sulphuric acid contains 196g of sulphuric acid

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

thats how its supposed to be
