Molar mass of SeOBr2 with work (PLEASE HELP ME!)

Explanation:

The molar mass is the mass of 1 mole of particles in a substance. We can calculate using values on the Periodic Table.

First, identify the elements in the compound: SeOBr₂.

Use the Periodic Table to find the molar masses.

Notice the formula has a subscript of 2 after bromine. This means there are 2 moles of bromine in 1 mole of SeOBr₂.

To calculate the molar masses, multiply bromine's molar mass by 2, then add selenium and oxygen.

The molar mass of SeOBr₂ is 254.679 grams per mole.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
