Calculate the mass of 0139 moles of copper?
Mass = moles x formula mass Mass = 0.139 x atomic mass of copper (63.5) Mass = 8.83g
How many moles in 32g of oxygen gas?
The number of grams in a mole of a molecule is found by looking at the atomic mass of each element on the periodic table. The molar mass of an element is it's atomic mass in grams. The atomic mass of oxygen is 15.999. Since there are two atoms of oxygen in a molecule of oxygen, the molar mass of oxgen (O2) is 15.999 x 2. That comes out to 31.998g/mol, or you can round to 32 if significant figures arn't important to you.
Calculate the number of moles in 112 g of iron?
Molar mass of iron is 56g. Given mass of iron= 112g No. of moles = Given mass/Molar Mass => 112g/56g= 2 moles
What is the total mass of oxygen 1.00 mole of AI2CrO43?
In this molecule, there are 4 oxygen atoms, so 1 mole of this substance would have 4 moles of oxygen atoms. Each oxygen atom is 16 g/mole, so 64 grams.
How many moles of oxygen are represent in 0.16 g of oxygen gas?
using the equation moles=mass/molar mass (since its in gas form) O2 => 16*2 =32 0.16/32=0.005 moles :)
What is the mass of 0.05 moles of an oxygen molecule?
1.6g
How you can find the mass of 3 moles of oxygen atoms?
The mass of one mole of oxygen atoms is listed on the periodic table (15.999g). Multiply this by three. Be careful. Oxygen is almost never found outside of a molecule. If you are looking for the mass of three moles of oxygen gas, that is three moles of O2. So, you will need to multiply the mass of the atom by two, then multiply by the number of moles.
What is the mass of 0.2 moles of oxygen gas?
The mass of 0,2 moles of oxygen gas is 6,4 g.
What is 42 grams of diatomic oxygen in moles?
moles = mass/molar mass The molar mass of an oxygen atom = 16 g mol-1, as there are two oxygen atoms in diatomic oxygen this has to be doubled. 42g / 32g mol-1 = 1.3125 moles
How do you calculate the number of moles when given the mass of a compound?
I assume you mean that you know what molecule it is, and how many grams of the substance you have, and want to know how many moles of the molecule you have.1. Count how many atoms of each chemical element are present in the molecule.2. Use a list of atom weights to find out the atom weight of each of the present atoms, i.e. the mole weight for every atom.3. Add together the mole weight of the atoms in the molecule. This is the molecule weight.4. Divide the weight of the substance you have with the molecule weight, and you will get the number of moles.Example: I have 500.0 g of ethanol. How many moles is that?1. The chemical formula of ethanol is C2H5OH, so every molecule consists of two carbon atoms, six hydrogen atoms and one oxygen atom.2. I use a book to look up the atom weights, and find out that the following:Carbon weighs 12.01 g/moleHydrogen weighs 1.008 g/moleOxygen weighs 16.00 g/mole3. (2 * 12.01) + (6 * 1.008) + (1 * 16.00) = 46.0684. 500.0 g / 46.068 g/mole = 10.85 moles
Calculate the mass of 0139 moles of copper?
Mass = moles x formula mass Mass = 0.139 x atomic mass of copper (63.5) Mass = 8.83g
How many moles are in 1.2 mg of oxygen?
The molar mass of oxygen is 32 g.1,2 mg oxygen is equal to 0,0000375 moles.
How many moles in 32g of oxygen gas?

What mass of oxygen gas contains the same number of moles as 56 gram of Sulphur?
28 mass of oxygen
How many moles of oxygen are represent in 0.16 g of oxygen gas?
using the equation moles=mass/molar mass (since its in gas form) O2 => 16*2 =32 0.16/32=0.005 moles :)
