Whats the mass concentration of H2SO4 in a solution with percent mass 36% and density 1.84g/cm3
W(H2SO4)=36%?
density(H2SO4)=1.84g/cm3
MassConcentration=?
Exactly what do you mean by mass concn. You have 36% which is mass concn to me.
If you want molarity it is done this way.
1.84 g/cc x 1000 cc x 0.36 x (1 mol/molar mass) = moles/L = M.
To find the mass concentration of H2SO4 in the solution, you need to use the given information of the percent mass and density.
First, let's calculate the mass of H2SO4 in a given volume of the solution. The percent mass of H2SO4 is given as 36%, meaning that in 100g of the solution, 36g is H2SO4.
To calculate the mass of H2SO4 in the solution, you need to know the volume. Since the density is given as 1.84g/cm3, you can assume 1 cm3 of the solution is equal to 1 gram.
Now, you can set up the calculation as follows:
Mass of H2SO4 = (Percent mass/100) * Volume of solution
Let's assume you have 100 cm3 of the solution:
Mass of H2SO4 = (36/100) * 100g = 36g
The mass of H2SO4 in 100 cm3 of the solution is 36g.
Finally, to calculate the mass concentration, you divide the mass of H2SO4 by the volume of the solution:
Mass concentration = Mass of H2SO4 / Volume of solution
Mass concentration = 36g / 100 cm3 = 0.36 g/cm3
Therefore, the mass concentration of H2SO4 in the solution is 0.36 g/cm3.
