How many moles of strontium chloride are includes in 20 ml of 0.2 moles strontium 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.
How many moles of Al would be produced from 20 moles if Al2O3?
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.
How many mole of h2 will be produced from the complete reaction of 20 mole of al?
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.
How many grams of barium chloride are needed to make 20 mL of a 2m solution?
To prepare a 2 m solution of barium chloride (BaCl₂), you need to know the molarity (moles per liter) and the molecular weight of BaCl₂, which is approximately 208.23 g/mol. For a 2 m solution, you need 2 moles per kilogram of solvent. Since 20 mL is 0.02 kg, you would need 0.04 moles of BaCl₂ (2 moles/kg × 0.02 kg). Multiplying 0.04 moles by the molar mass (208.23 g/mol) gives approximately 8.33 grams of barium chloride.
How many moles in 20g of magnesium nitrate?
There are 0.13 moles in 20 grams of magnesium nitrate.
What can make 20 moles of sodium chloride?
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.

The formula of 20 moles of sodium chloride?
The chemical formula of sodium chloride is NaCl; formula is not dependent from the number of moles. Because the molecular mass of NaCl is 57,958 622 382, the mass of 20 moles is 1159,172 447 64.

There are 0.13 moles in 20 grams of magnesium nitrate.
How many moles of sodium hydroxide are required to neutralize 20 mol of nitric acid?
First write down the BALANCED reaction equ'n. NaOH + HNO3 = NaNO3 + H2O We note the molar ratios are all ' 1:1 :: 1:1. So correspondingly 20 moles(HNO3) requires 20 moles (NaOH). By ratio 1:1 :: 20:20 NB By correspondence, the reaction will produce 20 moles (NaNO3) and 20 moles(Water/H2O). 20:20 :: 20:20
How many moles of H2SO4 are in 20 ml of 4 M solution?
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.
How many moles of N2 are there at a temperature of 20 degrees Celsius 1 ATM pressure if the gas occupies 44 Liters?
The answer is 1,83 moles.
How many grams of iron are in 20 moles of carbon monodxide?
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.
