Answer:
3 mol AlCl₃.
Explanation:
Hello!
In this case, according to the specified reactants and products, it is possible to set up the following balanced chemical reaction:
Whereas we evidence the 1:3 mole ratio between aluminum nitrate and sodium chloride; thus, since different moles were reacting, we need to identify the limiting reactant by computing the moles of AlCl₃ produced by each reactant as follows:
Thus, we infer that NaCl is the limiting reactant as it produces the fewest moles of AlCl₃; consequently the produced amount of this product is 3 mol.
Best regards!
Answer:
0.38 moles He
Explanation:
from the ideal gas law PV= nRT you can calculate the volume of 1 mole at STP (273..1K and 1 atm of pressure) the MOLAR VOLUME IS
22.4 L
In the problem you have 8.4L
8.4 L/22.4 L=0.375 moles
so
0.38 moles He
The solubility of a substance is defined as the maximum amount of solute that will dissolve in a specified amount of solvent at a specified temperature.
The maximum amount of a solute that can be dissolved in a solvent at a particular temperature and pressure is called its solubility. This is because for gases, the solubility decreases as the temperature increases.
Solubility is expressed as: Mass of solute per volume (g/l)
Mass of solute per mass of solvent (g/g)
Moles of solute per volume (mol/l)
The symbol for solubility is Ksp. The concentration of a solute in a saturated solution is equal to the solubility of the solute at that temperature.
