Answer 1

To determine the percent ammonia in the compound Co(NH3)6Cl3, calculate the molar mass of the compound and ammonia, then find the ratio between the two masses to determine the percent composition.

Step-by-step explanation:

To determine the percent ammonia in Co(NH3)6Cl3, we need to calculate the molar mass of the compound and the molar mass of ammonia. Then we can find the ratio between the two masses to determine the percent composition.

The molar mass of Co(NH3)6Cl3 is the sum of the molar masses of cobalt, ammonia, and chlorine, which are found from the periodic table. The molar mass of ammonia (NH3) is calculated by adding the molar masses of nitrogen and hydrogen.

Once we have the molar mass of ammonia and the molar mass of Co(NH3)6Cl3, we can calculate the percent ammonia by dividing the molar mass of ammonia by the molar mass of Co(NH3)6Cl3 and multiplying by 100.
