Neon molecule is mono-atomic.
20.18 g (1 mole) of neon will have 6.023 x 1023 atoms of neon
To calculate the number of moles of particles present in a sample, you need to divide the sample's mass by the molar mass of the particles. If you specify the particles as N'O, you should provide the molar mass of N'O for an accurate calculation.
48,5 g sample of CS2 is the equivalent of 0,637 moles.
A 63,60 g sample of carbon is equal to 5,296 moles.
350 g sample of CO contain 12,49 moles.
85.2 gram LiF sample is equivalent to 3,28 moles.

48,5 g sample of CS2 is the equivalent of 0,637 moles.
A 63,60 g sample of carbon is equal to 5,296 moles.
31,3 g sample of anhydrous CaSO4 equal 0,23 moles.
To determine the number of lb-moles in a sample, divide the weight of the sample in pounds by the molecular weight of the substance. This will give you the number of lb-moles present in the sample.
350 g sample of CO contain 12,49 moles.
To determine how many moles of magnesium are in a sample of 56.4 g, you would first calculate the molar mass of magnesium (about 24.3 g/mol). Then, divide the mass of the sample by the molar mass to obtain the number of moles present (around 2.32 moles in this case).
85.2 gram LiF sample is equivalent to 3,28 moles.
To find the number of moles in a sample, divide the sample's weight by the molar mass of the substance. In this case, if the sample weighs 5 grams and the molar mass is 30 g/mol, the number of moles present in the sample would be 0.167 moles.
This is equivalent to 0,36 moles.
1 mole of substance contains 6.02 x 1023 of its constituent particles. Accordingly, there would be 5.85 moles (of the substance) in a sample containing 3.52 x 1024 particles.
To find the number of moles in a sample, divide the sample's mass by the substance's atomic mass unit (amu). For a substance with an amu of 12, the number of moles in the sample can be calculated by dividing the sample's mass by 12.
