The density of the solid is 6.724 g/ml.
Density is the number of factors which can be people, animals, vegetation, or objects in a sure place. To calculate density, you divide the number of objects by the dimension of the place. The populace density of a rustic is the wide variety of human beings in that us of a divided by means of the location in square kilometers or miles.
The density of an amount to being counted is its mass divided by means of its quantity. it also includes measured at zero °C and at 1 atmosphere of stress. Density is vital in figuring out the buoyancy of materials in fluids, as well as in evaluating materials and other measurements.
The density of an object is certainly one of its maximum crucial and easily-measured physical properties. Densities are extensively used to perceive natural substances and to represent and estimate the composition of many varieties of combos.
density = mass/ volume
= 975g/145ml
= 6.724 g/ml

It takes about 24 hours for it to do that.
7.5 mol of hydrogen would be needed to consume the available nitrogen.
Explanation:
When hydrogen reacts with nitrogen, ammonia is formed as shown below;
3H₂ (g) + N₂ (g) → 2NH₃ (g)
As seen from the equation, every 3 moles of H₂ react with a mole of N₂ to form 2 moles of NH₃.
The limiting factor in a chemical reaction is the reactant that gets depleted first.
Because the molar mass of nitrogen gas is approximately 28g/mol, 70g of nitrogen gas would be 2.5 moles.
The reaction ratio of nitrogen to hydrogen in the reaction is 1 : 3. The reaction would require 2.5 * 3 (7.5) moles of hydrogen for a complete reaction.
However since there are only 7g on hydrogen, (Remember 1 mole of H₂ is approximately 2g), the available moles of H₂ is 7 / 2 = 3.5
3.5 moles fall short of the 7.5 moles of H₂ required for a complete reaction. H₂ gets depleted first before N₂. The reaction would require 4 more moles of H₂.
It’s a nonet because an octet is 8, a quartet is 4, and a duet is 2.
