How many g i2 should be added to 750g ccl4 to prepare a 0.200m solution?

Mass of I2 required = 38.1 g

Explanation:

Given:

Mass of CCl4 = 750 g = 0.750 kg

Molality of the solution = 0.200 m

To determine:

Mass of I2

Formula:

Molality of a solution is expressed as the ratio of the amount of solute per kg of solvent

Here the solute is I2 and solvent is CCl4

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
