If you have 10g each of Na C Pb Cu and Ne. Which contains the largest number of moles?
This element is carbon.
How many Moles of NaOH equals the moles of KHP?
The same number of moles for each.
Is the moles of atom and moles of molecule is same?
The number of units indicated by each description of moles of atoms and moles of molecules is the same and is specifically Avogadro's Number, about 6.022 X 10^23
How many moles of water are produced if 5.43 mol PbO2 are consumed?
Each mole of PbO2 contains 2 moles of oxygen (O). Thus there would be 5.43x2 = 10.86 moles O.Each mole of water (H2O) contains 1 mole of O, so from 10.86 moles of O you could get 10.86 moles of H2O.
How many mole of HCL will be required to react with potassium heptaoxodichromateiv to produce 3 moles of chlorine?
Six moles of HCl will be required: Each mole of chlorine contains two chlorine atoms, but each mole of HCl contains only one chlorine atom and the other reagent noted contains no chlorine atoms.
If you have 10g each of Na C Pb Cu and Ne. Which contains the largest number of moles?
This element is carbon.
How many moles of fluorine in 3 moles of borontrifluoride?
Boron trifluoride is BF3. So each mole of BF3 contains 1 moles of boron (B) and 3 moles of fluorine (F). Thus, 3 moles of BF3 contains NINE moles of fluorine.
How many moles of pottasium are in 125g of KCl?
The formula given shows that each formula unit of KCl contains one atom of potassium. Therefore, the number of moles of potassium will be the same as the number of moles of KCl, and its gram formula mass is 74.55. therefore, the number of moles is 125/74.55 or 1.68, to the justified number of significant digits.
How many Moles of NaOH equals the moles of KHP?
The same number of moles for each.
How many moles of C3H8 contains 9.25 times 10 to the 24 power molecules of C3H8?
By the definition of Avogadro's Number, each mole contains 6.022 X 1023 molecules. Therefore, (9.25 X 1024)/(6.022 X 1023) or 15.4 moles are required, to the justified number of significant digits.
How many moles of calcium atoms are 2.5 moles of calcium carbonate CaCO3?
The formula given shows that each formula unit or mole contains one calcium atom; therefore, 2.5 moles of calcium chloride contains 2.5 moles of calcium atoms.
Is the moles of atom and moles of molecule is same?
The number of units indicated by each description of moles of atoms and moles of molecules is the same and is specifically Avogadro's Number, about 6.022 X 10^23

Each mole of PbO2 contains 2 moles of oxygen (O). Thus there would be 5.43x2 = 10.86 moles O.Each mole of water (H2O) contains 1 mole of O, so from 10.86 moles of O you could get 10.86 moles of H2O.
How do you balance equtions?
Make sure that the number of moles of each element on the left is equal to the number of moles of the same element on the right.
Does the total number of moles reactants necessarily equal the total number of moles of product?
No. Take the microbial hydrogen mechanism as an example:4H2 + CO2 --> CH4 + 2H2O5 moles of reactants on the left converts to 3 moles of products on the right. The total number of moles of each type of atom does balance however.
What is the empirical formula of a compound that contains 4.0 g of hydrogen and 28 g of nitrogen?
Step 1: Convert the mass of each element to moles.4.0g H x 1mol H/1.00794g H = 4.0 moles H28g N x 1mol N/14.0067g N = 2.0 moles NStep 2: Divide each mole value by the smallest number of moles calculated.H = 4.0 moles/2.0 moles = 2N = 2.0 moles/2.0 moles = 1Empirical Formula = NH2
How many mole of HCL will be required to react with potassium heptaoxodichromateiv to produce 3 moles of chlorine?
Six moles of HCl will be required: Each mole of chlorine contains two chlorine atoms, but each mole of HCl contains only one chlorine atom and the other reagent noted contains no chlorine atoms.
