What is the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
What the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
What is a molar mass of a molecule?
The molar mass of a molecule is the sum of atomic weights of the elements contained in this molecule.
The vapour density of a gas is 11.2 so the volume occupied by 11.2 gm of the gas at NTP is?
vapour density of a gas= mass of a substance at STP/mass of a hydrogen at STP11.2= 1 gm molecule of a substance/2g11.2*2=1 gm molecule of a substance22.4g=1 gm molecule of a substance22.4g occupies Lt. at STPtherefore 11.2g occupies Lt.*11.2g/22.4g=11.2Lt.
Change gm to kg?
Divide (gm) by 1,000 to get the same mass in (kg).
Is gm equal to weight?
No. It is the mass.
What is the molar mass of a molecule?
The mass of one mole of substance, usually in grams or kilograms
What is gm is measurement?
'gm' may refer to a gram, a thousandth of a kilogram, a unit of mass.
How much iron will be present in one molecule of hemoglobin if hemoglobin has 0.25 percent by mass iron and the molecular mass of hemoglobin is 89600u?
If a quarter of the mass of the molecule is iron and the mass of the molecule is 89600u, then the mass of iron is 22400u ... a quarter of the total mass.
Can Atomic mass be used to determine molecular mass?
Yes, the accumulation of atomic masses of the atoms within a molecule is the molecule's molecular mass.
