Empirical formula mass

C2H4NO
2(12)+4(1)+14+16
30+24+4
58g/mol

Molar mass=232.2g/mol

Find n

Molar mass/Empirical formula mass
232.2/58
4

Molecular formula

n×Empirical formula
4(C2H4NO)
C8H16(NO)_4

A 3.0 L solution contains 73.5 g of H2SO4. Calculate the molar concentration of the solution.

kozerog [31]

$C_{m}=\frac{m}{MV}=\frac{73,5g}{98\frac{g}{mol}*3L}=0,25M\\\\
C_{1}V_{1}=C_{2}V_{2}\\\\
0,25M*3L=0,18M*V_{2}\\\\
V_{2}=\frac{0,25M*3L}{0,18M}\approx 4,17L\\\\
4,17L-3L=1,17L$

The enthalpy change of the reaction when sodium hydroxide and sulfuric acid react can be calculated using the mass of solution, temperature change, and specific heat of water.

The balanced chemical equation for the reaction can be represented as,

$H_{2}SO_{4}(aq) + 2NaOH (aq) ----> Na_{2}SO_{4}(aq) + 2H_{2}O(l)$
