How many molecules are there in 1.00 mol of H2O2?
There are 6.022x10^23 molecules in 1.00 mol of anything.
How do I calculate mass of H2O2 solution?
Mass of hydrogen = 1 g/mol Mass of oxygen = 16 g/mol There are 2 hydrogen in H2O2 and 2 oxygen in H202, so (1x2) + (16x2) = 34 g/mol
In the reaction 2H2O2-2H2O O2 if you start with 4 mol of H2O2 how many moles of O2 will you end up with?
4H2O2 --> 4H2O + 2O2 That would be 2: one mol of O2 for every 2 mols of H2O2.
The number of molecules of hydrogen peroxide found in 3.15 mol of H2O2 is?
3.15 X 6.02X10^23 = 1.89X10^24 molecules
How many atoms are in 1 mole of zinc atoms?
3 moles of Zn is equal to 18.09x1023 atoms. I used Avogadro's Number : 6.03x1023 particles/mol This number is the number of atoms or molecules in a mol of any substance. 3 moles X 6.03x1023 particles/mol = 18.09x1023 atoms
How many molecules are there in 1.00 mol of H2O2?
There are 6.022x10^23 molecules in 1.00 mol of anything.
Find the number of representative particles in 3.00 mol Sn?
1.80x10^24 moleclules of Sn

4H2O2 --> 4H2O + 2O2 That would be 2: one mol of O2 for every 2 mols of H2O2.
How many Oxygen atoms in 4.42mol of H2O2?
6023*10^23*4.
The number of mol of 6 percent hydrogen peroxide?
H2o2
What contains the greatest number of molecules out of 0.5 mol CaNO32 or 2.3 mol H2O or 1.2 mol H2O2?
The answer is 2,3 moles water.
How many representative particles are in 4.51 g of a molecular compound with a molar mass of 273 grams?
4.51 g x 1 mol x 6.022 x 1023 molecules = 9.95 x 1021 molecules .............273 g ............... 1 mol
A compound formed of 0.059 mol hydrogenand 0.94 mol oxyegn has a molecular mass of 34.0what is the molecular formula of this compound?
H2o2
A compound formed of 0.059 mol hydrogen and 0.94 mol oxygen has a molecular mass of 34.0 gmole What is the molecular formula of this compound?
h2o2
How do you determine the normality of a hydrogen peroxide solution?
Normality - a unit of concentration, it focuses mainly on the H+ and OH- available in an acid-base reaction. Normality can be found by using the formula Normality =Equivalents / LitersOtherwise known as N = equiv/LEquivalent of an acid - amount of acid that can furnish 1 mol of H+ ionsEquivalent of a base - amount of base that can furnish 1 mol of OH- ionsEquivalent weight - The mass (in grams) of one equivalent of an acid or base1) Look at the subscript to figure out the equivalent acid, or how many H+ or OH- can be furnished in one mol. The subscript will help you find the equivalent weight.In this case, the formula is is H2O2.it can furnish 2 mol of H+ ions per molecule. One mol of H2O2 can furnish two mol of H+. However we only need one mol of H+. Therefore, divide by two. 1/2 mol H2O2 = 1 equivalent of H2O22) Divide by however many Liters you have.
Arrange the following from the smallest number of representative particles to the largest number of representative particles1.25x1025 atoms of Zn 3.56 mol Fe 6.78x1022 molecules of glucose?
6,78.1022 molecules of glucose 2,14388229924.1024 iron atoms 1,25.1025 zinc atoms
