Its 4 dude i did this already
If we convert the ounces to grams, there are approximately 283.495 grams of plant fertiliser
If nitrogen has 15% of this, all we have to do is divide this number by 100 to get the mass of 1% and multiply it by 15.
In the end, we end up with the mass of 42.5243 g
Hope I helped! xx

Answer: Option (B) is the correct answer.
Explanation:
Molar mass is defined as the sum of masses of all the atoms present in a compound.
For example, atomic mass of barium is 137.32 g/mol and atomic mass of bromine is 79.90 g/mol.
Therefore, molar mass of
will be as follows.
Molar mass = atomic mass of Ba +
= 137.32 g/mol + 
= 297.12 g/mol
Hence, we can conclude that molar mass of [tex]BaBr_{2}[tex] is 297.12 g/mol.
