How many moles of potassium chloride are formed from 7 mol of HCl?
7: Molecules of HCl and KCl have the same number, 1, or chlorine atoms per mole; therefore, if HCl reacts completely with potassium, the same number of moles of potassium chloride as the number of moles of hydrogen chloride present will be formed. (For an ionic compound such as KCl, the term "formula unit" is preferable to "mole", but the mathematical consequences are the same.)
The number of moles of MgO produced when 0.200 mol of O2 reacts completely with magnesium is?
0.4 moles MgO
According to the following balanced reaction how many moles of NO are formed from 8.44 moles of NO2 if there is plenty of water present?
Balanced equation. 3NO2 + H2O -> 2HNO3 + NO 8.44 moles NO2 (1 mole NO/3 moles NO2) = 2.81 moles NO formed
How many moles of NaCl are formed from the reaction between 1.4 moles of HCl and 2.8 moles NaOH?
1.4 moles - the HCl is the limiting ingredient
When 0.5 moles of Na2SO4 is dissolved in water how many moles of sodium ions are present?
Since the formula shows two sodium atoms in each formula unit of sodium sulfate and this compound normally completely ionizes in water solution, the number of sodium ions will be twice the number of moles of the salt; in this instance, 1.0 moles of sodium ions.
How many moles of Na2Cro4 are contained in 74.3 grams of the compound?
74.3 g Na2CrO4 x 1 mole/162 g = 0.459 moles (3 sig figs)
300.0 Ml of water is added to .40 L of a .400 M Na2CrO4 solution what is the molarity of the resulting solution?
300.0 ml of water is added to .40 L of a .400 M Na2CrO4 solution what is the molarity of the resulting solution? Na2CrO4 = 2 Cr +Cr + 4 O's Molar mass = (2*23 + 52 + (4*16) = 162 A .400 M N Na2CrO4 solution has .400 moles of Na2CrO4 in a liter of water. .400 moles of Na2CrO4 = 0.400 * 162 = 64.8 grams of Na2CrO4 in a liter of water. Since you only have .40 L, you have 64.8 grams/liter * 0.4L = 25.92 grams of Na2CrO4 in 0.4 liter of solution. When you add 300.0 ml of water, you have total of 700 ml of solution. You still have 25.92 grams of Na2CrO4, but now you have 700 ml of solution. Molarity = moles of solute per liter of solution. Moles of solute = grams of solute ÷ Molar mass of solute Moles of solute = 25.92 ÷ 162 = 0.16 moles of Na2CrO4. Molarity = 0.16 moles of Na2CrO4 ÷ 0.700 L of solution. Molarity = 0.23 M
How many moles of Na2Cro4 are contaned in 74.3 Grams?
moles = weight (in g) / molecular weight (in g/mol) = 74.3 / 161.97 = 0.46 moles
How many moles of carbon dioxide are formed from 14 moles of methane?
When methane undergoes complete combustion, the equation for the reaction is CH4 + 2 O2 -> CO2 + 2 H2O. This shows that the number of moles of carbon dioxide formed are the same as the number of moles of methane reacted, so that 14 moles of carbon dioxide will be formed from 14 moles of methane.
How many moles of potassium chloride are formed from 7 mol of HCl?
7: Molecules of HCl and KCl have the same number, 1, or chlorine atoms per mole; therefore, if HCl reacts completely with potassium, the same number of moles of potassium chloride as the number of moles of hydrogen chloride present will be formed. (For an ionic compound such as KCl, the term "formula unit" is preferable to "mole", but the mathematical consequences are the same.)
How many moles of sodium chromate (Na2CrO4) are contained in 1.75L of a 2.00m solution?
Assuming you mean 2.00 M and not 2.00 m, then moles of sodium chromate would be as follows:1.75 L x 2.00 moles/L = 3.50 moles sodium chromate
What is the total number of moles of NO produced when 1.0 mole of O2 is completely consumed?
The total number of moles of NO produced when 1,0 mole of O2 is completely consumed is 2.
The number of moles of MgO produced when 0.200 mol of O2 reacts completely with magnesium is?
0.4 moles MgO
What is the total number of moles of electrons lost by the copper as it completely reacts with 8 moles of nitric acid?
ahsu
What is the total number of moles of Ca needed to react completely with 4.0 moles of water?
Ca + 2 H2O ------> Ca(OH)2 + H2 so 2 moles of calcium react with 4 moles of water.
How does limiting reagent affect how much product is formed?
The amount of product will be limited by the number of moles of the limitin... reagent.
What is the number of moles of Cl ions combine completely with 0.25 molesof Mg 2 ions is?
20.4
