Is the empirical formula molar mass less than or equal to the actual molar mass for all compound?
The empirical formula molar mass is the mass of the simplest whole-number ratio of the elements in a compound, while the actual molar mass corresponds to the molar mass of the compound's molecular formula. The empirical formula molar mass is always less than or equal to the actual molar mass because the empirical formula represents the smallest ratio of atoms, which can be multiplied to obtain the molecular formula. Therefore, for compounds with a molecular formula that is a multiple of the empirical formula, the empirical molar mass will be less than the actual molar mass.
If some of the gas bubbles escape the volumetric flask during the experiment atmosphere. Would the calculated molar mass of the gas be greater or less than the theoretical molecular value?
If gas bubbles escape the volumetric flask, the calculated molar mass of the gas will be less than the theoretical molecular value. This is because the number of moles of gas remaining in the flask will be underestimated, leading to a lower molar mass calculation.
Is oxygen molecular mass twice of its atomic mass?
Molar mass of it is 32gmol-1. It is twice than an atom.
How does burning candle affect mass differently than melting a candle?
When a candle burns, it undergoes a chemical reaction called combustion, where the wax reacts with oxygen to produce carbon dioxide and water vapor. During this process, the candle's mass decreases as some of the wax is converted into gases. On the other hand, when a candle melts, it transitions from solid to liquid state, but its mass remains unchanged as no chemical reaction occurs.
Does one mole of NH3 weigh more than one mole of H2O?
The mass of NH3 mole = its molecular weight = 14 + 3 x 1 = 17 The mass of H2O mole = its molecular weight = 2 x 1 + 16 = 18 This means that one mole of NH3 weigh less than one mole of H2O

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.
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).

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.
Is oxygen molecular mass twice of its atomic mass?
Molar mass of it is 32gmol-1. It is twice than an atom.
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.

Can a candle float on olive oil?
Yes, a candle can float on olive oil if the candle is made of a material that is less dense than the oil and is designed to be buoyant. The wax used in candles is typically less dense than oil, allowing them to float. However, the wick and the candle's overall design can affect its buoyancy. If the candle absorbs enough oil or water, it may eventually sink.
Why can a candle float on water?
Because wax is less dense than water.
Does one mole of NH3 weigh more than one mole of H2O?
The mass of NH3 mole = its molecular weight = 14 + 3 x 1 = 17 The mass of H2O mole = its molecular weight = 2 x 1 + 16 = 18 This means that one mole of NH3 weigh less than one mole of H2O
Is the weight-mass of a CD more or less than a kg?
The mass is less than 1 kg.
