What is the mass of K 42 remaining in a 16g sample of 37.2hrs?
2.09
What mass of oxygen contians the same number of molecules as 42g of nitrogen?
as 1 mole of ni trogen = 14g thereforre are 3 moles of nitrogen in 42g, similarly 1 mole of oxygen is = 16g therefore 3*16 =48 g
What is the mass of 0.7891 mol of ferric oxide (Fe2O3)?
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
Which molecule has more mass H2O or CO2?
CO2 has more than twice the mass of H2O. One Hydrogen atom weighs around 1 unit, while an oxygen atom is around 16 so a Water molecule is around 18 units. Carbon has around 12 units of mass. When you add the two Oxygen Molecules you get 44 units of mass for each CO2 molecule.
What is the mass of 0.7891 mol of ferric oxide?
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
What is the atomic mass of Hydrogen Nitrogen and oxygen?
hydrogen-1g nitrogen-14g oxygen-16g
What is the mass in grams of 1mole of oxygen?
The mass of 2.000 mol of oxygen atoms is 32.00 grams.
How many number of moles of carbon dioxide that are contain 16g of oxygen?
As one mole of CO2 contain 2 oxygen having molar mass 32. Soo there will be 0.50 moles of CO2 which contain 16g of oxygen....!
If 16g of oxygen contains 1 mole of oxygen atoms calculate the mass of one atom of oxygen in grams?
1
What is the mass of oxygen in grams?
15.994 grams/mol, but it can rounded to 15.99 or 16.0 g/mol.
What is the mass of K 42 remaining in a 16g sample of 37.2hrs?
2.09
What is the density of a 0.016 kg silver bracelet that has a volume of 9.27cm cubed?
0.016kg = 16g Density = Mass/Volume 16g/9.27cm = 1.726g/cm3
What is the mass of a powder if the combined mass of the powder and it’s container is 12 grams and the mass of the container alone is 4 grams?
16g
How many moles are in 16g NaCI?
1 mole of NaCI = Mass of Na 23 , Mass of C 12, Mass of I 127 = 23 + 12 + 127 = 162g therefore : if 162g = 1 mole 16g = ? 1 x 16/ 162 = 0.098
How many grams of O2 are in 50moles of the oxygen gas?
Ar of O = 16g/mol Mr of O2 = 2(16) = 32g/mol Using the formula : mass = Mr x number of moles mass = 32g/mol x 50mols = 1600g
If the mass of the cube is 16g what is its density?
The density of an object is its mass divided by its volume. Without the volume, you cannot calculate its density.
What is the the formula mass of the compound H2SO4?
mass H= 1.01g mass S= 32g mass O= 16g Total mass = 2(H) + S + 4(O) = 98.02g
