What is the mass of 1 mole of a compound?
The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.
What mass unit is 1 mole?
The molar mass of a substance is the mass of 1 mole of that substance, in multiples of the gram. The amount of substance is the number of moles in the sample. For most practical purposes, the magnitude of molar mass is numerically the same as that of the mean mass of one molecule, expressed in daltons.
What is a gram mole?
(Often called gram-molecular weight.) A mass of a substance in grams numerically equal to its molecular weight. Example: A gram-mole of salt (NaCl) is 58.44 grams.
How do you find the moles of a compound?
Determining Number of Moles of a Compound With Known Mass
To find the number of moles in a sample, simply weigh it and divide the weight by the molecular weight. The quotient is equal to the number of moles.
What is the mass of 0.5 mole of so2?
16 amu. Step-by-step explanation: One mole of sulphur contains 32 amu. so 0.5 mole will have 16 amu.
What is the moles of h2so4?
The molar mass of sulfuric acid is 98.07848 g mol.
