How many atoms are in 0.455 moles of lead?
Atomic mass: 207.2 grams.455 moles × (6.02 × 1023) = 2.74 × 1023 atoms of lead
What is the molecular formula of the molecule that has an empirical formula of CH2O and a molar mass of 120.1g?
The molecular mass of a compound with the formula CH2O is approx. 30, not 120.
What is the mass of 0.25 moles of aluminum sulphate?
What is the mass of 0.25 moles of aluminum sulfate
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
Convert 1.3 moles of calcium to grams?
52.1grams. moles = mass (in grams)/RMM (relative molecular mass) 1.3 moles = mass (in grams)/ 40.078 mass = 40.078 x 1.3 = 52.1grams
How many molecules of CH2O are in 50.0 g of CH2O?
Molar mass of CH2O = 12 + 2 + 16 = 30 g/mole50.0 g x 1 mole/30 g = 1.67 moles
How many grams in 2 moles of methane?
The amount of grams in two moles depends on the element or compound that you have two moles of. For example, the molar mass of oxygen is about 16 grams. So two moles of oxygen would be about 32 grams.
How many atoms are in 0.455 moles of lead?
Atomic mass: 207.2 grams.455 moles × (6.02 × 1023) = 2.74 × 1023 atoms of lead
What is the molecular formula of the molecule that has an empirical formula of CH2O and a molar mass of 120.1g?
The molecular mass of a compound with the formula CH2O is approx. 30, not 120.
How many moles of Pt are in a 455-mg ring of pure platinum?
.3
How is the number of moles determined from a known mass?
Number of moles = Total mass/Molar mass
How do you find moles of hydrogen?
Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given. or No. of moles= Given mass of substance/Molar mass of substance
How many moles are there in 5gram of sulphur?
Atomic mass of Sulphur is 32 1 mole = Atomic mass of sulphur No. of moles = Given mass/ Atomic mass No.of moles= 5/32 0.15 moles
Formula for moles?
number of moles = mass of the material/molar mass
What is the mass of 0.25 moles of aluminum sulphate?
What is the mass of 0.25 moles of aluminum sulfate
What is the mass of 15 moles of tungsten?
The mass of 15 moles of tungsten is 2.757,6 g.
What is the mass of 2.4 moles of chlorine?
The mass of 2,4 moles of chlorine is 84,08 g.
