Answer:
in 4 liters of solution
MgSO4) are dissolved in 0.965 L of a 0.0575 M solution? Molar Mass Mg: 24.30 g/mol Molar Mass S: 32.06 g/mol Molar Mass O: 16.00 g/
Answer:
860 J / mol
Explanation:
Enthalpy = Energy / no. of moles
no. of moles = mass / molar mass
Take the atomic mass of H = 1.0,
molar mass of H2 = 1.0 x 2
= 2.0
no. of moles of H2 = 9.00/2
= 4.5 mol
Hence,
Enthalpy = 3870 / 4.5
=860 J / mol
B. horizontally Thats the answer
