H₂O (water) has a lower relative molecular mass than CS₂ (carbon disulfide) because the molecular mass of H₂O is approximately 18 g/mol (composed of two hydrogen atoms and one oxygen atom), while CS₂ has a molecular mass of about 76 g/mol (comprising one carbon atom and two sulfur atoms). The difference in the number and mass of the constituent atoms results in H₂O having a significantly lower molecular weight compared to CS₂.
What else can I help you with?
Is oxygen molecular mass twice of its atomic mass?
Molar mass of it is 32gmol-1. It is twice than an atom.
What are the relative atomic mass of subatomic particles in atom?
The relative atomic mass of electrons is considered negligible, as they are much lighter than protons and neutrons. Protons and neutrons each have a relative atomic mass of approximately 1, as they are found in the nucleus of an atom and contribute to its overall mass.
Is air more dense than oil?
No. density is based on molecular mass. Air is considered a gas. Gases have lower densities than liquids at 'room temperature'.
Is molecular weight the same as mass?
Technically... not really. It would perhaps be more accurate to use the terms formula mass and molecular mass rather than formula weight and molecular weight. This because in physical terms, weight is a force while mass is a measure of the amount of substance in something.
Is the molecular mass of candle wax less than 100?
No, the range is about 282-562 molecular mass for candle wax.
True or false Gases with high molecular weights diffuse more slowly than gases with lower molecular weights?
True. Gases with high molecular weights have slower diffusion rates compared to gases with lower molecular weights due to their larger mass and lower average speed of the molecules.
How does the molecular mass affect freezing point depression?
The molecular mass of a solute affects freezing point depression because larger molecules disrupt the formation of solid crystals more than smaller molecules, leading to a lower freezing point for the solution.
What has more mass water or sulfuric acid?
The molecular maass of sulfuric acid (98,08) is greater than the molecular mass of water (18).
What is likely to happen to a molecular cloud core with a mass that is less than its Jeans Mass?
If a molecular cloud core has a mass less than its Jeans Mass, it is unlikely to collapse under gravity to form a star. The core may remain stable or disperse due to external factors such as turbulence or thermal pressure. A lower mass core may not have enough self-gravity to overcome these opposing forces and initiate star formation.
Which gas effuses faster at the same temperature molecular oxygen or atomic argon?
Molecular oxygen will effuse faster because: Molar Mass of O2: 32g Atomic Mass of Ar: 40g
Is oxygen molecular mass twice of its atomic mass?
Molar mass of it is 32gmol-1. It is twice than an atom.
Which product has the largest molecular mass sodium acetate water or carbon dioxide?
Sodium acetate has a larger molecular mass than water or carbon dioxide. Water has a molecular mass of 18 g/mol, carbon dioxide has a molecular mass of 44 g/mol, and sodium acetate has a molecular mass of 82 g/mol.
What are the relative atomic mass of subatomic particles in atom?
The relative atomic mass of electrons is considered negligible, as they are much lighter than protons and neutrons. Protons and neutrons each have a relative atomic mass of approximately 1, as they are found in the nucleus of an atom and contribute to its overall mass.
Does oxygen have a greater mass than chlorine?
Atomic oxygen does not have a greater atomic mass than chlorine, nor does molecular oxygen. The atomic mass of chlorine is approximately 35 g/mol, while molecular (O2) oxygen has a molecular mass of 32 g/mol.
What is the moleculer mass of a gas that diffuses through a porous membrane 1.86 times faster than Xenon what might the gas be?
The molecular mass of the unknown gas is likely half that of xenon since diffusion rate is inversely proportional to the square root of the molecular weight. Xenon has a molecular weight of 131.29 g/mol, so the unknown gas could have a molecular weight of around 65.65 g/mol.
What has lower melting points than ionic solids?
Molecular solids
Is butane gas less volatile than propane?
Yes, the molecular mass of propane is 44 while that of butane is 58, higher is the molecular mass of an alkane higher would be the boiling point therefore less would be the volatility.
