How many moles are in 342g sucrose?
To calculate the number of moles in 342g of sucrose, divide the given mass by the molar mass of sucrose. The molar mass of sucrose (C12H22O11) is approximately 342.3 g/mol. Therefore, 342g of sucrose is equal to 1 mole.
The formula for sucrose is C12H22O11. Figure the molar mass of sucrose to the nearest gram?
For this you need the atomic (molecular) mass of C12H22O11. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. C12H22O11= 342 grams.105 moles C12H22O11 × (342 grams)= 35.9 grams C12H22O11
Molar mass of sucrose?
It depends upon how much you have, but its molar mass is about 342g/mol, meaning 1 mole of table sugar (sucrose, C12H22O11) has a mass equal to the sum of all the molecule's constituent elements.
Which has the largest mass A 3 mol of magnesium B 1 mol of sucrose c12h22o11 C 10 mol of helium?
Since magnesium and helium do not form elemental molecules, a mole of these elements is the same as a gram atomic mass, which is 24.305 for magnesium and 4.00260 for helium. The gram molecular mass for sucrose is 342.30. Therefore, the mass of: A. 3 moles of magnesium is 72.915 grams; B 1 mole of sucrose (C12H22O11) is 342.30 grams; and C. 10 moles of helium is 40.0260 grams. The largest of these is obviously the single mole of sucrose.
How do you make a 1 molar solution of sucrose?
To make a 1 molar solution of sucrose, you would weigh out 342.3 grams of sucrose (molecular weight of sucrose is 342.3 g/mol) and dissolve it in water to make a final volume of 1 liter. This would give you a solution where 1 mole of sucrose is dissolved in 1 liter of water.
What is the mass of 7.08x1020 molecules of sucrose?
You divide 7.08ee10^20/6.022ee^23 = .0011756891 then you times that number by the grams of sucrose(C12H22O11) .0011756891 X 342 = .402g of C12H22O11

What is the molecular formula of sugar?
It depends on the kind of sugar you are talking about. If you are talking about glucose or fructose, the molecular formula is C6H12O6 (glucose and fructose only differ in structure but have the same formula). Sucrose, which is common table sugar, has the molecular formula C12H22O11. Scientifically, the word "sugar" is used for any mono- or di-saccharide. Sugar added in food is called sucrose. Sugar naturally found in fruit is called fructose.
Which has the largest mass A 3 mol of magnesium B 1 mol of sucrose c12h22o11 C 10 mol of helium?

How many grams of sucrose (C12H22O11) are in 1.55 L of 0.758 M sucrose solution?
1 litre is 1000ml therefore 15g per 100ml would equal 150g per 1000ml. So 3 Litres would contain 450g.
How many grams of oxygen are in 100.0g sucrose?
Ideal gas equation: pV=nRT STP is 298K (temperature) and 1 ATM (pressure). Use the ideal gas equation to calculate the number of moles of oxygen in 2L at STP. Complete oxidation means that the molecule is oxidised to carbon dioxide and water. Sucrose is C12H22O11 meaning is will be oxidised to 12 carbon dioxide and 11 water molecules (it has 12 carbon atoms and 22 hydrogen atoms in). To produce these, it will need 12x2 + 11 oxygen atoms. Since 11 atoms are already present in the sucrose, it requires an additional 24 atoms of oxygen per molecule of sucrose. One mole is a fixed number of atoms, so the ratio will stay the same. Hence 1 mole of sucrose requires 24 moles of oxygen to oxidise it fully. Divide the number of moles of oxygen you have calculated are present in the 2L by the number of moles of oxygen required to fully oxidise the sucrose (24). This tells you how many moles of sucrose you can fully oxidise with your oxygen. m=n x Mr The mass is equal to the number of moles multiplied by the relative molecular mass. You can therefore multiply your result by the molecular mass of sucrose to find how many grams of sucrose you can fully oxidise. Molecular mass is the addition of the atomic masses of each of the atoms in a molecule. Sucrose has a molecular mass of 342.3 grams/mole.
How many grams of carbon are in 100.0g of sucrose?
Well, honey, sucrose is made up of carbon, hydrogen, and oxygen. Carbon makes up about 40% of the molecular weight of sucrose, so in 100.0g of sucrose, you'd have about 40.0g of carbon. Just remember, sugar might be sweet, but chemistry sure ain't.

The formula for surcrose is C12H22O11. figure the molar mass of sucrose to the nearest gram.?
The formula for sucrose is C11H22O11. To figure this out, you need to list the elements in the compound along with the amount of times it is in the compound and the atomic masses of the elements, like so... Carbon 11 12 132 Hydrogen 22 1 22 Oxygen 11 16 176 Add the right column all up and you get 330. So, to reiterate, sucrose has a molar mass of 330 to the nearest gram.
What mass of sucrose C12H22O11 should be combined with 472 g of water to make a solution with an osmotic pressure of 8.95 ATM at 300K?
I finally figured out how to answer this question if you still need the help for it. you use the osmotic pressure equation: TT = (M)(R)(T) R= .08206 L*ATM/mol *k (this is your constant) T= temperature in Kelvin 300K TT=Pressure in ATM 8.95 Now you have to (M) Molarity. 8.95atm/.08206*300= .3635 mols/1L now multiply that in a chain of conversions= 0.3635mols/L*342.12 g/mol(MM of sucrose)*472ml(grams of water since 1g is equal to 1ml)= 58698 and then divide by 1000 to cancel out L and ml= 58.69g of sucrose Now add this to your grams of water = 472+58.69=530.69g ( the question says you have so and so water in a solution so that's why you add the sucrose to get your amount of solution needed) that mass 530.69 you convert to Liters= .53069L and then multiply that with your molarity at the top and you cancel out Liters and left with mols= .1929 mols. then find the mass of sucrose needed by multiplying the .1929 mols* 342.12g and theres your answer.
