What term describes how much matter a substances contains?
Mass decribes how much matter a substance contains and Mole decribes the quantity of matter contained in a substance.
How is a mole related to the atomic mass?
The atomic mass, in grams, is the mass of one mole of atoms.
What is 0.1 mol per liter?
It refers to a solution each litre of which contains one tenth of a mole of a particular substance. A mole is a specific number of atoms or molecules - 6.02 x 10 to the power of 23, also known as Avogadro's number. One mole of any substance has a mass equal to its atomic or molecular weight expressed in grams. Thus, one mole of Helium has a mass of 2g; one mole of Sodium Chloride - NaCl - has a mass of 22.98g + 35.45g = 58.43g. It follows that a 0.1 molar solution of NaCl contains 5.843g of NaCl in each litre of solution.
Do coefficient balanced equations give mass to mass relationships?
No they give mole ratios. A mole is much like a dozen, a dozen is 12 while a mole is 6.02*10^23. This means that 1 mole of a substance represents 6.02*10^23 molecules of that substance.
Why you do find it useful to have two units for the amount of substance the kilogram and the mole?
Kilogram and mole really measure to very different things. Kilogram is used to measure the mass; the mole is closely related to the number of particles. 1 mole of a substance always has (number of Avogadro) particles. Therefore, you can't say in general that a kilogram is so-and-so many moles; this depends on the substance. For example, a mole of hydrogen atoms has a mass of 1 gram, while a mole of oxygen atoms has a mass of 16 grams.
What term describes how much matter a substances contains?
Mass decribes how much matter a substance contains and Mole decribes the quantity of matter contained in a substance.
how do we measure how much of a substance we have?
Molar mass of a substance is the mass of one mole of the substance in grams. It has a unit of grams per mole (g mol -1). One mole of any substance contains 6.02 × 10 23 particles. Therefore, the molar mass of a substance contains 6.02 × 10 23 particles of the substance.
How many moles are there in 98.1 g of H2SO4?
1 mole Since H2SO4's molar mass is 98.1g, and a substance's molar mass contains exactly 1 mole, that is the answer
What term describes how matter a substance contain?
Mass decribes how much matter a substance contains and Mole decribes the quantity of matter contained in a substance.
Molar is the total combined mass of a mole of a substance?
mass
How are molarity and molar mass related for a compound?
The molar mass of a substance is measured in grams per mole written as gmol-1. It is worked out using the Mole formula by dividing mass in grams by the amount in moles.
Define one mole of a substance applied to atomic structure?
A mole is used to measure the amount of substance.1 mole of any substance contains 6.023 x 1023 molecules of that substance. 1 mole of a substance has mass equal to the atomic weight or molecular weight expressed in grams. Note:The number "6.023 x 1023" is called Avogadro's Number
How is a mole related to the atomic mass?
The atomic mass, in grams, is the mass of one mole of atoms.
The mass of one mole of substance called its?
chicken nuggets
What is the SI unit for the amount of a substance that contains as many particles as there are atoms in exactly 12 grams of carbon -12?
mole
How many atoms are in 1 mol of au?
Regardless of the substance, one mole contains the Avogadro's number of parts of the particular substance.
How many moles of barium are present in a sample having a mass of 22.3 grams?
# of moles = grams of substance / molar mass of substance molar mass of Barium =137.33 grams/mole #moles of Barium = 22.3 grams/ 137.33 grams/mole = 0.162382582 moles
