The element helium does not technically have "moles", because its atomsdo not form any chemical bond with other helium atoms. Its formula unit is a single atom. Avogadro's Number, the number of formula units in a gram Atomic Mass, is about 6.022 X 1023. Therefore, 1.20 x 1025 atoms constitutes (1.20 X 1025)/(6.022 X 1023) or about 19.9 formula masses, to the justified number of significant digits.

How many monosaccharides make up this molecule C 120H 238O 119?
This molecule has 120 carbon (C) atoms, 238 hydrogen (H) atoms, and 119 oxygen (O) atoms. To determine the number of monosaccharides making up this molecule, we need additional information such as the molecular formula of the monosaccharide or the structure of the molecule. Without this information, we cannot provide an exact answer.

What mass of F2 is needed to produce 120g of PF3 if the reaction is 78.1?
To determine the mass of F2 needed to produce 120 g of PF3, we first need to calculate the molar mass of PF3, which is approximately 88 g/mol (phosphorus = 31 g/mol, fluorine = 19 g/mol × 3). The balanced chemical reaction for producing PF3 from P and F2 is: P + 3F2 → PF3. Since the molar ratio of PF3 to F2 is 1:3, we need 3 moles of F2 for every mole of PF3 produced. Therefore, for 120 g of PF3, which is about 1.36 moles (120 g / 88 g/mol), we would require approximately 4.08 moles of F2, or about 164 g (4.08 moles × 38 g/mol for F2).

How many moles of sodium hydroxide are found in 120 grams of Na OH?
The mole of a metal, such as sodium, is generally assumed to consist of Avogadro's Number of single atoms. The gram atomic mass of sodium is 22.9898. The number of moles in 120 grams of Na is therefore 120/22.9898, or 5.22, rounded to the justified number of significant digits.
How many moles of sodium are in 120 grams?
To find the number of moles in 120 grams of sodium, divide the given mass by the molar mass of sodium. The molar mass of sodium is approximately 23 grams per mole. Therefore, 120 grams of sodium is equal to 120/23 ≈ 5.22 moles of sodium.
How many molecules of bromine are present in 120 grams of bromine gas?
To determine the number of molecules in 120 grams of bromine gas, you first need to calculate the moles of bromine using its molar mass (molar mass of Br2 = 159.808 g/mol). Then, use Avogadro's number (6.022 x 10^23) to find the number of molecules in that many moles of bromine gas.
