This is what you are looking for.
300 grams C6H12O6 (1 mole C6H12O6/180.156 grams)(6 mole C/1 mole C6H12O6)(6.022 X 10^23/1 mole C)(1 mole C/6.022 X 10^23)
= 9.99 moles Carbon atoms in that mass glucose
300 grams C6H12O6 (1 mole C6H12O6/180.156 grams)(12 mole H/1 mole C6H12O6)(6.022 X 10^23/1 mole H)(1 mole H/6.022 X 10^23)
= 19.98 moles Hydrogen atoms in that mass glucose
Now, you have seen two examples of this procedure, so you do the oxygen number crunching.

How many atoms are found in 600 grams of iron?
To find the number of atoms we need to find number of moles of Fe in 312.0 grams. Molar weight of Fe = 56 Number of moles of Fe in 312 grams = 312/56 =5.571 moles. 1 mole of Fe has Avogadro number of atoms. So 5.571 moles of Fe has atoms = 5.571 * Avogadro number. Avogadro number = 6.022 * 10^23 So total atoms = 5.571 * 6.022 * 10^23 = 33.548 * 10^23 * means multiply, ^ means raised to power.
What is the approximate molar mass of a molecular solute if 300 g of the solute in 1000 g of water causes the solution to have a boiling point of 101C?
The change in boiling point can be used to calculate the molality of the solution. Using that molality value, you can then calculate the moles of the solute in 300g. Finally, dividing the mass by the moles gives the molar mass, which is approximately 150 g/mol.
How many grams of N2F4 can be produced from 225gF2?
I love the smell of stoichiometry in the morning! The answer is approximately 300g of N2F4, and here's how you get it:Step 1: Get an equation for this reaction. Your product is obviously N2F4 (dinitrogen tetrafluoride), and one of the two reactants is F2 (diatomic fluorine gas). The other reactant has to be nitrogen, so you set up and balance a synthesis reaction equation:N2 + 2F2 --> N2F4Step 2: Get the number of moles of your reactant by setting up a direct proportion with the atomic mass of fluorine:39g/1mol=225g/x, solve for x to get 5.77 moles of fluorine.Step 3: Work the molar ratio in the reaction equation to see that you need half as many moles of product as you have of fluorine reactant:5.77/2=2.89 moles N2F4Step 4: Set up another direct proportion with the molar mass of product, which is 104g/mol:104/1=x/2.89, solve for x to get 300.5g, so the answer is approx. 300g of N2O4.Some things to remember in this calculation:- don't forget your diatomics- watch your equation balancing- label all numbers with correct units so you can keep track of them
At what Kerlvin temperature will 300 g of sugar dissolve in water?
The solubility of sugar in water increases with temperature. At 20°C, 300g of sugar can dissolve in water, while at a higher temperature like 80°C, more sugar can dissolve. The exact temperature at which 300g of sugar will dissolve in water depends on the water temperature and the saturation point of sugar in water at that specific temperature.
How much heat must be added to 300 grams of water at 100 degrees C to convert it to steam at 100 degrees C?
q = m•Hv, where q is amount of energy added, mis mass in grams, which is 300g, and Hv is heat of vaporization of water, which is 2260 J/g .q = 300g x 2260 J/g = 678 000 Joules

What is the molality of a solution that has 70g of NaCl dissolved in 300g of water?
Molality(m)= moles of solute divided by kilograms(kg) of solvent you need to find the moles of NaCl by using a conversion factor 70g NaCl = 1mol divided by 58.44g NaCl =1.20mol then you need to convert 300g of water which is the solvent to kilograms by moving the decimal over 3 units to the left which makes .300 kg of solvent Molality= 1.20mol divided by .300kg Molality=4.00
