How many atoms of H are in 2 mol of c8h18?
2 moles C8H18 (18 moles H/1 mole C8H18)(6.022 X 10^23/1 mole H) = 2.2 X 10^25 atoms of hydrogen
How many moles of O2 are needed to burn 1.50 moles of C8H18?
Balance this combustion reaction first! 2C4H10 + 13O2 -> 8CO2 + 10H2O 0.86 moles C4H10 (13 moles O2/2 moles C4H10) = 5.6 moles of oxygen required ----------------------------------------
How many moles of ions are produced when 2 mol of Na2CO3 dissociate?
Na2CO32 * 2 = 4 moles sodium.===========================
How many grams of NO are produced from the reaction of 2 mol of N2 with 2 mol of O2?
You have :N2 + O2 -----> 2NOmoles NO = ( 2 mols N2 reacted ) ( 2 mol NO / mol N2 reacted )moles NO = 4 moles NOmass NO = ( 4 mol NO ) ( 30 g NO / mol NO ) = 120 g NO
How many moles of KBr will be produced from 4.79 moles of BaBr2?
14.17 mol BaBr2 has 2*14.17 mol Br in it, so 28.34 mol KBr can be produced (also 28.34 mol K is needed)
How many atoms of H are in 2 mol of c8h18?
2 moles C8H18 (18 moles H/1 mole C8H18)(6.022 X 10^23/1 mole H) = 2.2 X 10^25 atoms of hydrogen
How many moles of carbon and hydrogen are there in 5 moles of octane?
Balanced equation. 2C8H18 + 25O2 -> 16CO2 + 18H2O 5.5 moles C8H18 (25 moles O2/2 moles C8H18) = 68.75 moles O2 needed
How many moles of water can be produced by burning 325g of octane in excess oxygen?
Balanced equation: 2C8H18 + 25O2 ==> 16CO2 + 18H2Omoles of octane used: 325 g x 1 mole/114g = 2.85 moles octanemoles H2O produced: 18 moles H2O/2 moles C8H18 x 2.85 moles C8H18 = 25.65 moles H2O
How many moles of O2 are needed to burn 1.50 moles of C8H18?
Balance this combustion reaction first! 2C4H10 + 13O2 -> 8CO2 + 10H2O 0.86 moles C4H10 (13 moles O2/2 moles C4H10) = 5.6 moles of oxygen required ----------------------------------------

How many grams of NO are produced from the reaction of 2 mol of N2 with 2 mol of O2?
You have :N2 + O2 -----> 2NOmoles NO = ( 2 mols N2 reacted ) ( 2 mol NO / mol N2 reacted )moles NO = 4 moles NOmass NO = ( 4 mol NO ) ( 30 g NO / mol NO ) = 120 g NO
How many moles of potassium bromide can be produced from the reaction of 2.92 moles of potassium with 1.78 moles of bromine gas?
First write a balanced chemical equation: 2K + Br2 ---> 2KBR Find the limiting reactant by using the moles of each element and determining which one gives you the smallest number of moles of potassium bromide. 2.92 mol K (2 mol KBr/2 mol K)= 2.92 mol KBr 1.78 mol Br2 (2 mol KBR/1 mol Br2)=3.56 mol KBr potassium is your limiting reactant so the max. number of moles of KBr that can be produced is 2.92 mol of KBr
How many moles of KBr will be produced from 4.79 moles of BaBr2?
14.17 mol BaBr2 has 2*14.17 mol Br in it, so 28.34 mol KBr can be produced (also 28.34 mol K is needed)
How many moles of KBr will be produced from 14.17 moles of BaBr2?
14.17 mol BaBr2 has 2*14.17 mol Br in it, so 28.34 mol KBr can be produced (also 28.34 mol K is needed)
What is the theoretical yield in grams of CO2 from the reaction of 4.000 moles of C8H18 with 4.000 moles of O2 Chemical equation 2 C8H18 plus 25 O2------ 16 CO2 plus 18 H2O?
2 of octane react with 25 of oxygen so 12.5 moles of O2 react with 1 mole of C8H18.
How many moles of HCl are dissolved in 2.0 L of 0.25 M HCl solution?
0.5 Moles If you have a 0.25 M solution, you have 0.25 mol/dm3, or 0.25 moles in 1 L (0.25 mol/L) If you have 2 L of solution, you have 2 L x 0.25 mol/L = 0.5 mol The L's cancel out, and you're left with moles.
How many mol of Ca2 plus ions are in 2.8 mol of Ca3N2?
2.8 moles Ca3N2 (3 mole Ca 2+/1 mole Ca3N2) = 8.4 moles Ca 2+ =============
