# 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.

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 molecular mass of n2?

NitrogenPubChem CID: 947 Chemical Names: Nitrogen; Nitrogen gas; Molecular nitrogen; 7727-37-9; Nitrogen-14; Dinitrogen More Molecular Formula: N _{2}Molecular Weight: 28.014 g/mol InChI Key: IJGRMHOSHXDMSA-UHFFFAOYSA-N #### How many neutrons are in the element argon?

Argon's atomic number is**18**, so it has**18 protons**; in the neutral (ordinary; un-ionized) atom, there are therefore**18**electrons. The neutron number depends on which isotope you're considering. The argon on Earth is chiefly 4°Ar, so it has**22 neutrons**.

B.

### What is the molar mass of argon?

39.948 u ± 0.001 u

#### What is the atomic mass of helium gas?

Helium's atomic mass is 4.003, (carbon is 12.0107, oxygen is 15.9994). Multiply the atomic mass number by the molar mass constant (defined as 0.001 kg/mol. or 1 gram/mol.), thus making the molar mass**4.003 grams**/mol.#### Is argon toxic?

Although**argon**is non-toxic, it is 38% denser than air and therefore considered a**dangerous**asphyxiant in closed areas. It is difficult to detect because it is colorless, odorless, and tasteless.#### How many balloons would it take to lift a 120 pound person?

If you weigh 50 kilograms (about 110 pounds), then you weigh 50,000 grams. Divide your 50,000 grams by the**14**grams per balloon and you find that you need**3,571.42 balloons**to lift your weight.

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.#### How many molecules are there in 1 mole of a substance?

The**mole**, abbreviated**mol**, is an SI unit which measures the number of particles in a specific substance. One**mole**is equal to (6.02214179 imes 10^{23}) atoms, or other elementary units such as**molecules**.#### What is the mass in grams of 5.90 mol?

96 g/mol.

What is the mass in grams of 5.90 mol C8H18? mass = 5.90 x 114 =**672.6**g which can be rounded to 673g.

What is the number of moles in**432g**Ba(NO3)2?#### How is Amu defined?

An atomic mass unit (symbolized**AMU**or**amu**) is**defined**as precisely 1/12 the mass of an atom of carbon-12. The carbon-12 (C-12) atom has six protons and six neutrons in its nucleus. In imprecise terms, one**AMU**is the average of the proton rest mass and the neutron rest mass.
