There are 0.13 moles in 20 grams of magnesium nitrate.
To determine how many moles of aluminum (Al) are produced from 20 moles of aluminum oxide (Al2O3), we need to use the balanced chemical equation for the reduction of Al2O3. The equation is: 2 Al2O3 → 4 Al + 3 O2. From this, we see that 2 moles of Al2O3 produce 4 moles of Al. Therefore, from 20 moles of Al2O3, we can calculate that 20 moles of Al2O3 would produce 40 moles of Al.
To find the number of moles of strontium chloride in 20 mL of a 0.2 M solution, you can use the formula: moles = concentration (M) × volume (L). First, convert 20 mL to liters, which is 0.020 L. Then, calculate the moles: 0.2 moles/L × 0.020 L = 0.004 moles of strontium chloride.
The solubility of poassium nitrate in water at 20 oC is 616 g/L.
The answer is 1,83 moles.
There are 0.13 moles in 20 grams of magnesium nitrate.

To make 20 moles of sodium chloride, you would need 20 moles of sodium ions and 20 moles of chloride ions. This could be achieved by combining 40 moles of sodium atoms with 40 moles of chlorine atoms to form 20 moles of sodium chloride.
To find the number of moles of strontium chloride in 20 mL of a 0.2 M solution, you can use the formula: moles = concentration (M) × volume (L). First, convert 20 mL to liters, which is 0.020 L. Then, calculate the moles: 0.2 moles/L × 0.020 L = 0.004 moles of strontium chloride.
The balanced chemical equation for the neutralization between sodium hydroxide (NaOH) and nitric acid (HNO3) is 1 mol of NaOH reacts with 1 mol of HNO3. Therefore, 20 moles of nitric acid would require 20 moles of sodium hydroxide to neutralize it.
To find the number of moles of H2SO4 in 20 ml of 4 M solution, we first need to calculate the number of moles present in 20 ml of the solution using the formula: moles = Molarity x Volume (L). Converting 20 ml to liters (20 ml = 0.02 L) and then calculating moles: 4 M x 0.02 L = 0.08 moles of H2SO4.
The solubility of poassium nitrate in water at 20 oC is 616 g/L.
The answer is 1,83 moles.
In carbon monoxide (CO), the molar ratio of carbon (C) to oxygen (O) is 1:1. Therefore, in 20 moles of CO, there are 20 moles of carbon. The molar mass of carbon is approximately 12.011 g/mol, so in 20 moles of carbon, there are 20 x 12.011 = 240.22 grams of carbon.
Quinine is a drug with chemical formula C20H24N2O2. In each molecule of quinine there are 20 carbon atoms. Thus in 4.0 moles of quinine, there would be 80 moles of carbon.
The chemical formula for potassium nitrate is KNO3, which means that one molecule contains five atoms. Therefore, four molecules of potassium nitrate would contain 20 atoms.
20 moles of Al will react with water to form 60 moles of H2 and 30 moles of O2, because of the stoichiometry 2:1 in getting H2 en O2 from water, and Al needing an oxidationstate of 3+, so 1 mole is oxidized by 3 moles of H2O.
