Question

Визначити масову частку алюміній два о три​

Answer 1

Ответ:

Mr(Al2O3) =2Ar(Al)+ 3Ar(O)27*2+16*3= 102

w=nAr/Mr *100% сполуки

w(Al)= 54/102 * 100% = 53%

Answer 2

Determining the Mass Fraction of Aluminum

To determine the mass fraction of aluminum in a compound, we need to know the molar masses of the elements present in the compound and then use the formula for mass fraction.

The mass fraction of aluminum (Al) in a compound can be calculated using the following formula:

Mass Fraction of Aluminum (Al) = (Mass of Aluminum (Al) / Total Mass of Compound) x 100%

Let's calculate the mass fraction of aluminum using the provided information.

Calculation

From the provided search results, we don't have specific information about the compound or its molar masses. Therefore, without additional information, it's not possible to calculate the mass fraction of aluminum accurately.

If you have the specific compound and its molar masses, please provide that information, and I'd be happy to help you calculate the mass fraction of aluminum.
