2 moles O3 (48 grams/1 mole O3)
= 96 grams of ozone

Molar mass of iron is 56g. Given mass of iron= 112g No. of moles = Given mass/Molar Mass => 112g/56g= 2 moles
Balanced chemical equation along with the stoichiometric ratios derived from that chemical reaction. A + B --> 2C mass of A * 1/molar mass of A = moles of A Moles of A * 2 moles of C/mole of A = moles of C Moles of C * molar mass of C = mass of C Also, you must think about limiting reagents, because if there is not enought reactant B to react with the amount of reactant A then the amount of reactant B will limit the production of product C!
Amount of Br2 = mass of sample / molar mass = 160 / 2(79.9) = 1.00mol
using the equation moles=mass/molar mass (since its in gas form) O2 => 16*2 =32 0.16/32=0.005 moles :)
The mass of 2 moles of ethyl alcohol would be 92,14 grams.
Molar mass of iron is 56g. Given mass of iron= 112g No. of moles = Given mass/Molar Mass => 112g/56g= 2 moles
The molar mass of hydrogen is 2 g.
# moles = mass / molar mass = 1.23g / 83.80g/mol =1.47x10^-2 moles There are 1.47x10^-2 moles in 1.23g of krypton
molar mass =207.2 g / mol no. moles = mass/ molar mass moles = 1 1(207.2) = mass mass of 1 mole lead is 207.2g molar mass =207.2 g / mol no. moles = mass/ molar mass moles = 1 1(207.2) = mass mass of 1 mole lead is 207.2g
If you think to the molar mass this is 601,9237 g.
The molar mass, that is mass per mole is given in the periodic table. The mass of one Cl-atom is approximately 35,45g/mole. In Cl2 there are 2, henbce you multiply the molar mass with 2.

Molar mass of barium hydroxide, Ba(OH)2 = 171.3Amount of barium hydroxide = mass of sample / molar mass = 317.0/171.3 = 1.85mol
The molar mass of hydrogen is 2.
Amount of Br2 = mass of sample / molar mass = 160 / 2(79.9) = 1.00mol
You must first find the molar mass of the element or compound. Use the periodic table (see the link to the left of the answer). If the chemical is an element, just read off the atomic mass from the periodic table. If it is a compound, you must know the molecular formula, and then you find the total molar mass of the compound by adding up the atomic masses of each atom in the compound. The unit of the molar mass will be in grams per moles (g/mole)Once you have the molar mass, you can easily convert from grams to moles, and also from moles to grams.Number of moles = (# of grams) / (molar mass)Number of grams = (# of moles) * (molar mass)Here are a two examples:Example 1:How many moles are in 5 grams of O2?The molar mass of O2 = 16.00 g/mole x 2 (for 2 atoms of oxygen) or 32.00 g/mole.5 g of O2 / (32 g/mole) = 0.15625 molesExample 2:How many grams does 4 moles of NH3 weigh?The molar mass of NH3 = 14.01 + (3 * 1.01) = 17.04 g/mole4 moles * 17.04 g/mole = 68.16 grams Grams in a MoleIn chemistry a mole is considered to be Avogadro's number (6.02 x 1023)of molecules (or atoms) of a substance - so depending on the density of the substance, the mass of that amount of the substance could vary widely.One mole of hydrogen, for example, would have a different mass than one mole of lead. The question compares two different measurements of a given substance, rather like asking "how heavy is a gallon?". The question becomes "A gallon of what"?*On the other hand, the Eastern Mole (Scalopus aquaticus) a small, burrowing mammal, weighs between 54 and 99 grams at adult size.To convert grams to moles simply multiply the molar mass by the number of moles.
To convert moles of a substance into grams you first need to figure out its molecular mass. Then you can use this equation: grams(g)=moles(n) X molecular mass For example, 1 mole of Carbon (which has a molecular mass of 12) has a mass of 12 grams.
