To determine the cost of the mercury per cubic inch, we need to divide the total cost with the total volume in units of cubic inches. To do this, we first determine the volume of the mercury given the mass and the density. In any operation, it is important to remember that the units of the values involved should be homogeneous so that we can cancel them. We do as follows:
mass of mercury = 76 lb ( 1 kg / 2.2 lbs ) ( 1000 g / 1 kg ) = 34545.45 g
volume of mercury in cm^3 = 34545.45 g / 13.534 g / cm^3 = 2552.49 cm^3
We need to convert this to units of cubic inches since it is what is asked.
volume of mercury in in^3 = 2552.49 cm^3 ( 1 in / 2.54 cm )^3 = 155.76 in^3
cost per in^3 = $126 / 155.76 in^3 = $ 0.809 / in^3

Answer:
MgO
Explanation:
Mg, which is magnesium, is considered a metal, when paired with Oxygen, which is a gas, it creates magnesium oxide, and the formula itself is a pairing of a metal with a nonmetal
The compound HNO3 is called nitric acid.
HNO3 is a covalent compound and a strong acid which ionizes in water into H+ (proton) and NO3- (nitrate ion).
HNO3 (aq) ↔ H+(aq) + NO3-(aq)
Ans: HNO3 = Nitric Acid
[On a side note: Nitrous acid is HNO2]
I'm pretty sure the formula is 2n(/\) 2
