The mass of HCl that is contained in the solution is 147 g HCl
Why?
To find the mass of HCl we have to apply what is called a conversion factor. In a conversion factor we put the units we don't want at the bottom, and the ones we want at the top.
For this question, we want to go from liters of solution to mass of HCl, and the conversion factor is laid out as follows:

Answer:
79.4 kg
Explanation:
The formula for potassium iodide is:-

This means that they are present in the same mole ration, i.e. 1 : 1
Also for 2 samples, the ratio of the masses must be equal .
So,

Thus,
Mass of potassium in sample 1 = 13.0 g
Mass of Iodine in sample 1 = 42.3 g
Mass of potassium in sample 2 = 24.4 kg
Applying in the above formula, we get that:-

Mass of iodine in sample 2 = 79.4 kg
I think they are primary producers, as they produce biomass from inorganic compounds (CO2)
Answer:
There are 1.8021 ⋅ 1024 molecules of CH4 in 48 grams of CH4. To answer this question, you must understand how to convert grams of a molecule into the number of molecules. To do this, you have to utilize the concepts of moles and molar mass. A mole is just a unit of measurement. Avogadro's number is equal to 6.022 ⋅1023 molecules/mole. i think please dont complain to me if its wrong im sorry
Explanation:
Answer:
Option a → 4 mol NH₃
Explanation:
This the unbalanced reaction
NH₃ + O₂ ⟶ N₂ + H₂O
The balanced reaction:
4NH₃ + 3O₂ → 2N₂ + 6H₂O
4 mol of ammonia
3 mol of oxygen
2 mol of nitrogen
6 mol of water
