What is the molar mass of argon?

39.948 u ± 0.001 u
A.

What is the mass of one mole of argon?

How many grams Argon in 1 moles? The answer is 39.948.
  • How many atoms are there in argon?

    So for the element of ARGON, you already know that the atomic number tells you the number of electrons. That means there are 18 electrons in an argon atom.
  • What is the mass of a mole of helium gas?

    4.002602
  • Is argon diatomic?

    The noble gases (helium, neon, argon, krypton, xenon, and radon) are also gases at STP, but they are monatomic. Ditungsten (W2) and dimolybdenum (Mo2) form with sextuple bonds in the gas phase. The bond in a homonuclear diatomic molecule is non-polar. Dirubidium is diatomic.
B.

Is argon a solid liquid or gas?

Argon has approximately the same solubility in water as oxygen and is 2.5 times more soluble in water than nitrogen. Argon is colorless, odorless, nonflammable and nontoxic as a solid, liquid or gas. Argon is chemically inert under most conditions and forms no confirmed stable compounds at room temperature.
  • Is the element magnesium a solid liquid or gas?

    At STP (standard temperature and pressure) , magnesium is a solid. Therefore, it is considered a solid on the periodic table. The only two liquid elements at STP on the table are Mercury and bromine.
  • What are some interesting facts about Argon?

    Argon is the third most prevalent gas in the Earth's atmosphere, found at 9,300 parts per million. It makes up 1.28% of the Earth's atmosphere. It was the first noble gas to be discovered. Argon is a colorless, odorless, and non-toxic material in all three of its states.
  • Is lead a solid liquid or gas?

    Elements can be classified based on their physical states (States of Matter) e.g. gas, solid or liquid. This element is a solid. Lead is classified in the 'Other Metals' section which can be located in groups 13, 14, and 15 of the Periodic Table.
C.

What is the mass of one mole of sodium?

In this example, multiply the grams of Na by the conversion factor 1 mol Na/ 22.98 g Na, with 22.98g being the molar mass of one mole of Na, which then allows cancelation of grams, leaving moles of Na.
  • What is the mass of 1 mole of oxygen atoms?

    Oxygen's atomic weight is 16.00 amu. 1 mole of oxygen is 6.02 x 1023 atoms of oxygen 1 amu = 1.661 x 10-24g What is the molar mass (g/mole) of oxygen? Molar mass (in grams) is always equal to the atomic weight of the atom! Molar mass (in grams) is always equal to the atomic weight of the atom!
  • How many moles are in 02?

    The answer is 0.031251171918947. We assume you are converting between moles O2 and gram. 1 mole is equal to 1 moles O2, or 31.9988 grams.
  • How are the molar mass and atomic mass different from one another?

    "Molar mass" is used to describe the mass of one mole of a chemical compound, while "atomic mass" is used to describe the mass of one mole of an element or the mass of one atom of an element. "Grams/mole" is better, because any macroscopic amount of a substance is better expressed in grams than amu.
