What else can I help you with?
Does a gram of hydrogen or a gram of oxygen have the greater volume at the same temperature and pressure?
A gram of hydrogen has a greater volume than a gram of oxygen at the same temperature and pressure, as hydrogen has a lower molecular weight and therefore occupies more space per gram compared to oxygen.
What is the gram molecular mass of hydrogen?
The gram molecular mass of hydrogen is 1 gram per mole.
What is the gram molecular weight of Sodium hydroxide if its molecular mass is 40 a.m.u?
The a.m.u. is defined as the fraction of 1/12 of an atom of the carbon-12 isotope. The value is pretty nearer to the mass of a hydrogen atom. Therefore, in every compound, the gram molecular weight is numerically equal to the molecular mass in atomic mass units. Therefore the gram molecular weight of NaOH is 40 g/mol.
What is the gram molecular mass of a compound if 5 moles of the compound has a mass of 100 grams?
To find the gram molecular mass of the compound, you can use the formula: mass = moles × gram molecular mass. Given that 5 moles of the compound have a mass of 100 grams, you can rearrange the formula to find the gram molecular mass: gram molecular mass = mass / moles. Thus, gram molecular mass = 100 grams / 5 moles = 20 grams per mole.
What is the gram molecular weight for PbSO4?
The gram molecular weight of lead(II) sulfate (PbSO4) can be calculated by summing the atomic weights of its constituent elements: lead (Pb) has an atomic weight of approximately 207.2 g/mol, sulfur (S) is about 32.1 g/mol, and oxygen (O) is approximately 16.0 g/mol. The formula for PbSO4 includes one lead atom, one sulfur atom, and four oxygen atoms. Therefore, the gram molecular weight is calculated as follows: 207.2 + 32.1 + (4 × 16.0) = 303.3 g/mol.
What is the value of gram molecular volume of ozone at STP?
The gram molecular volume of ozone at STP (standard temperature and pressure) is approximately 22.4 L/mol.
Does a gram of hydrogen or a gram of oxygen have the greater volume at the same temperature and pressure?
A gram of hydrogen has a greater volume than a gram of oxygen at the same temperature and pressure, as hydrogen has a lower molecular weight and therefore occupies more space per gram compared to oxygen.
What is the difference between treaty v executive agreement?
molarity x molecular weight x volume=gram molarity= gram/molecular weight x volume abdulrazzaq
What is the gram molecular weight of 3.92 grams of oxygen?
62.72
What is the gram molecular mass of hydrogen?
The gram molecular mass of hydrogen is 1 gram per mole.
What is a gram of a molecular substance?
A gram of a molecular substance is the quantity that will have a mass of 1 gram.
What are the gram molecular weights ofC6H8O7?
gram molecular weight of C6H8O7=(atomic weigth of carbon X 6)+(atomic weigth of hydrogen X 8+(atomic weigth of oxygen X 7) grams
Is 200 gram cotton is equal to 200 gram of iron?
in weight : yes in value : no in volume : no in hardness : no
What is gram molecular weight of cabon dioxide?
The molar mass of CO2 is Mr (C)=12.01 Mr (0)=16.00 Therefore, the molar mass is (12.01+(16.00x2) since there are 2 oxygen atoms then the molar mass will be doubled for oxygen therefore, Molar Mass=48.01 g/mol
What is the gram molecular weight of Sodium hydroxide if its molecular mass is 40 a.m.u?

Given that 5 moles of the compound have a mass of 100 grams, you can rearrange the formula to find the gram molecular mass: gram molecular mass = mass / moles. Thus, gram molecular mass = 100 grams / 5 moles = 20 grams per mole.
Specific gravity of oxygen is?
Start with the molecular weight of oxygen, twice the atomic weight because it's O2. So the molecular weight is 32. Now at school you learn that a gram-mole of any gas occupies 22.4 litres. A gram-mole of oxygen weighs 32 grams (1 gram times the molecular weight). Therefore 32 grams of oxygen occupies 22.4 litres (at normal temperature and pressure). 22.4 litres of water (specific gravity = 1) weighs 22400 grams. Therefore the specific gravity is 32/22400 = 0.00142857 . . That's it!
