Question

A solution of 8.4 gm of a newly discovered compound (molar mass = 80000) in 75 ml of solution shows a temperature rise of $0.0 4^{\circ} C$ for complete oxygenation. Each mole of compound binds 10 moles of oxygen. If heat capacity of solution is 4.2 J/K- ml, then calculate amount of heat released per mole of oxygen bound in kJ.

Answer:

12.00

Solution:

$Q = \frac{75 \times 0.04 \times 4.2}{10 \times 8.4 \times 1000} \times 80000 = 12$

TestHub · Accepted Answer

Q = 10 × 8.4 × 1000 75 × 0.04 × 4.2 ​ × 80000 = 12
