Answer:
1.35×10¹² μg
Explanation:
Mass (Kg) = 1350 Kg
Mass (μg) =?
Thus, we can obtain the mass of the adult rhino in micrograms (μg) by converting 1350 Kg to microgram (μg) as follow:
1 Kg = 1×10⁹ μg
Therefore,
1350 Kg = 1350 kg / 1 kg × 1×10⁹ μg
1350 Kg = 1.35×10¹² μg
Therefore, 1350 Kg is equivalent to 1.35×10¹² μg.

Answer:
Atomic mass of N relative to H is 13.9.
In periodic table mass of N is around 14 RAM
Explanation:
1 mol of ammonia has 1 mol of N, and 3 mole of H
NH₃
1 mol of H weighs 1 g, so the mole of H, present in ammonia are:
1.712 g / 1 g/m = 1.712 mole
Since the ratio is 1:3
1.712 mole/3 = 0.57 mole of N are present in the amonia
To calculate the atomic mass of N relative to H, let's consider it as molar weight.
Molar weight = mass / mole
7.933 g / 0.57 mole = 13.9 g/m
The third equation is properly balanced.
To figure this out, set up tables to check if each element has the same amount on both sides. If you do this for the third equation, copper, hydrogen, oxygen, and nitrogen are all balanced,
The first equation is incorrect due to the fact Iron, Fe, is not balanced on both sides. This is shown by the subscripts given.
The second equation is incorrect as Sulfur is not properly balanced and neither is sodium.
The fourth equation is incorrect as Aluminum is not properly balanced. On the reactants side, Aluminum is 4 while on the products, Aluminum is 8.
Hope this helps!
