Question: – Which scientist first gave the idea of a molecule?
Answer: – Italian scientist Amidio Avogadro first came up with the idea of a molecule.
Question: – What is the volume of gas in STP?
Answer: – The molar volume of any gas in STP is 22.4 litres.
Question: – What is the Avogadro number? What is its value
Answer: – One gram molecule is the same number of molecules in any substance. This number is called the Avogadro number. Avogadro Number value: 6.023 x 1023.
Question: – What is the number of molecules in 32 g oxygen?
Answer: – Number of molecules in 32 g oxygen = 6.023 x 1023.
Question: – What is the molecular weight of gram of nitrogen? (N = 14)
Answer: – Molecular importance of nitrogen = 14 x 2 = 28. Gram molecular weight of nitrogen = 28 g.
Question: – What is the number of atoms in 12 grams of carbon?
Answer: – Number of atoms in 12 grams of carbon = 6.023 x 1023.
Question: – What is the number of atoms in 1 gram atom of oxygen?
Answer: – The number of atoms in 1 gram-atom oxygen = 6.023 x 1023.
Question: – What is the basic atomicity?
Answer: – The number of atoms in which a molecule of a element is made is called atomicity of that element.
Question: – What is the atomicity of weight gas?
Answer: – Atomicity of weight gas (O3) = 3.
Question: – What is the atomicity of argon gas?
Answer: – Atomicity of argon gas = 1.
Question: – Name a gaseous element whose molecules and atoms are synonymous?
Answer: – The name of the gaseous element is helium . Helium contains only one atom in a molecule.
Question: What is the molecular volume? What is the value of this in NTP?
Answer: – The proof is that the volume of a gram-molecule under the heat and pressure of any gas is called the volume of a molecule. The molecular volume in NTP is = 22.4 liters.
Question: – The vapor density of a gas is 8.5, what is the molecular importance of that gas?
Answer: – Molecular importance of gas = 2 x Steam density of gas = 2 x 8.5 = 17.
Question: – Who is the father of atomism?
Answer: – Sir John Dalton is the father of atomism .
Question: – What is the mass of 0.5 mole water?
Answer: – Molecular mass of water = 18; Therefore, 1 mole of water = 18 g.
So 0.5 moles of water = (18 x 0.5) grams of water = 9 grams of water.
Question: – What is the number of molecules in STP at 2 liters of carbon dioxide gas if NP is 6.023 x 1023?
Answer: – Since the molecule in H2 gas = 6.023 x 1023
Therefore 1 g of molecule H2 was taken.
Therefore the number of molecules in V-liter H2 = 6.023 x 1023
Therefore the molecule = 2 x 6.023 x 1023 in 2V liters of carbon dioxide.
Question: – The mass of a molecule of a compound is 5.65 x 10-23 grams. What is the molecular mass of the compound?
Answer: – The mass of 1 molecule of compound = 5.65 x 10-23 g.
Therefore the mass of the compound is 6.023 x 1023 – mass of molecules = 6.023 x 1023 x 5.65 x 10-23 g = 34.03 g (approx.).
So the molecular mass of the compound = 34.03.
Question: – V litres of oxygen and V in the same heat and pressure2Litter sulfur dioxide gas was collected. If the mass of 32 grams of oxygen collected V2What is the number of molecules in litre sulfur dioxide? (O = 16)
Answer: – 1 gram-molecule oxygen = 32 grams of oxygen.
