Answer: second option: mole ratio.
Explanation:
The coefficients of the chemical equation, when balanced, indicate the number ratio in which compounds combine with each other.
In the given equation, <span>Mg+2HCl -->MgCl₂+H₂
1 mole of Mg combines with 2 moles of HCl and produce 1 mole of MgCl₂ and 1 mol of H2.
So, the mole ratio is
1 mol Mg : 2 mol HCl : 1 mol MgCl₂ : 1 mol H₂.
In general, in a balanced equation of the kind aA + bB → cC + dD
The mole ratio is:
a mol of A : b mol of B : c mol of C : d mol D.

The moles of product are formed is 0.0303 mol
The process we are interested in is
3Mg + N2 to Mg3N2.
N(Mg3N2) = n(Mg)/3 = 0.0303 mol moles of product were produced.
<h3>What is Moles ?</h3>
A mole is the mass of a substance that includes 6.023 x 10^23 of that substance's particles. The mole is the SI unit used to measure a substance's quantity. It has the symbol mol. As a result: One mole of carbon-12 weighs 12 grammes and has a carbon atom content of 6.022140857 x 10^23.
- In particular, in terms of mass, it serves as a bridge between the microscopic and the macroscopic. A unit (atom or molecules) has the same mass in grammes as a mole of a substance has in atomic mass units.
Hence, moles of product are formed is 0.0303 mol

Answer:
1.d = 2.70 g/mL
2.d = 13.6 g/mL
4.d = 1896 g / 212.52 cm3 = 8.9 g/cm3
