How many moles in 20g of magnesium nitrate?
There are 0.13 moles in 20 grams of magnesium nitrate.
How many moles of potassium nitrate contain 8.68 x 1020 KNO3 formula units?
To find the number of moles of potassium nitrate (KNO3) from the given formula units, we use Avogadro's number, which is approximately (6.022 \times 10^{23}) formula units per mole. We can calculate the moles by dividing the number of formula units by Avogadro's number: [ \text{Moles of KNO3} = \frac{8.68 \times 10^{20}}{6.022 \times 10^{23}} \approx 0.00144 \text{ moles} ] Thus, there are approximately 0.00144 moles of potassium nitrate in 8.68 x (10^{20}) formula units.
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 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.

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.
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 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 grams of potassium nitrate can we dissolve in ml of water at A degrees Celsius?
The solubility of poassium nitrate in water at 20 oC is 616 g/L.
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.
How many moles fo carbon are in 5.0 moles of quinine?
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.
How many atoms are in four molecules of potassium nitrate?
