5 moles of carbon is 60,055 g.
5 moles of sodium is 114,949 g.
There are 5 formula masses of Na in 5 formula masses of NaCl, as indicated by the fact that the symbol for sodium has no explicit subscript in the formula of NaCl. Neither sodium nor sodium chloride has moles in the strictest sense, since neither of them is covalently bonded.
In 5 moles of octane, C8H18, there are 40 moles of carbon atoms (5 moles octane x 8 carbon atoms) and 90 moles of hydrogen atoms (5 moles octane x 18 hydrogen atoms).
The answer is 10 moles of carbon monoxide.2 C + O2 = 2 CO
Dividing by the molar mass of sodium carbonate, we deduce that there are 4.25 x 10-5 moles in 4.5 x 10-3 grams of sodium carbonate.
To calculate the number of moles in 1 teaspoon of sodium sulfide (Na₂S), you first need to know the mass of sodium sulfide in that teaspoon. Typically, a teaspoon holds about 5 grams of a substance, but this can vary based on the density of the compound. Once you have the mass, you can use the molar mass of Na₂S (approximately 78.04 g/mol) to find the number of moles by using the formula: moles = mass (g) / molar mass (g/mol). For example, if 1 teaspoon is 5 grams, then moles of Na₂S = 5 g / 78.04 g/mol ≈ 0.064 moles.
When 4 moles of sodium react with oxygen, 2 moles of sodium oxide are produced (according to the balanced equation). Therefore, when 10 moles of sodium react, 5 moles of sodium oxide will be produced.

1 mole of Sodium Chloride weighs 58.5 grams (1 mole is the same as the molecular weight of a compound. The molecular mass of Sodium Chloride- NaCl is 23 [Na atomic mass] + 35.5 [Cl atomic mass] which is equal to 58.5 grams).Thus 10 moles would weigh 10x58.5 grams = 585 grams.The answer is 585 grams.
There are 3 moles of sodium represented in one mole of sodium phosphate (Na3PO4). This is because the subscript 3 in Na3PO4 indicates that there are 3 sodium ions for every molecule of sodium phosphate.
The balanced chemical equation shows that 5 moles of carbon react with 2 moles of sulfur dioxide to produce 2 moles of carbon disulfide and 4 moles of carbon monoxide. Therefore, to react with 5.44 moles of sulfur dioxide, you would need 5.44 moles / 2 moles = 2.72 moles of carbon.
The answer is 10 moles of carbon monoxide.2 C + O2 = 2 CO
Dividing by the molar mass of sodium carbonate, we deduce that there are 4.25 x 10-5 moles in 4.5 x 10-3 grams of sodium carbonate.
For this you need the atomic mass of Na. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.11.5 grams Na / (23.0 grams) = .500 moles Na
To find how many grams of sodium carbonate contain 1.773 x 10^17 carbon atoms, you need to consider the molar ratio. Sodium carbonate (Na2CO3) has 1 carbon atom per molecule. Calculate the molar mass of Na2CO3, then use Avogadro's number to convert the number of carbon atoms to moles, and finally to grams.
The answer is o,5 mol.
Well you can see from your equation that each mole of heptane produces 7 moles of Carbon dioxide when burned so 5 moles of heptane produces 5 X 7 moles of carbon dioxide. I'll let you do the maths.
