When a solid reaches the temperature of its melting point, it can become a liquid. For water, the temperature needs to be a little over zero degrees Celsius (0oC) for you to melt. If you were salt, sugar, or rock, your melting point is higher than that of water.
To start off any questions, we write down the givens.
Mass CO2 = 168.2g
Molar Mass CO2 = <span>44.011g/mol
Moles CO2 = ?
To find the number of moles, we do mass/molar mass to find the # moles
n CO2 = 44.011g / 168.2 g/mol
n CO2 = </span>0.26165874 mol
n CO2 = 0.2617 mol
The number of moles in the sample is 0.2617 mol.
Tungsten, or wolfram, is a chemical element with symbol W and atomic number 74. The name tungsten comes from the former Swedish name for the tungstate mineral scheelite, tung sten or "heavy stone".

Answer: Glucose (C6H12O6) is a hexose -- a monosaccharide containing six carbon atoms. Glucose is an aldehyde (contains a -CHO group). Five of the carbons plus an oxygen atom form a loop called a "pyranose ring", the most stable form for six-carbon aldoses.
