# A sample of carbon dioxide has a mass of 35.2 grams What volume will this gas take up at STP?

First convert the number of grams of CO2 into moles, then use
the Ideal Gas Law. **For how to solve this problem, see the two

### How many moles of carbon are there from the original sample of 11.0 grams of carbon dioxide and 4.50 grams of water with a combustion of 7.50 grams?

Look up the molecular weight of carbon dioxide in the periodic table. The formula for carbon dioxide is CO2, which means one atom of carbon and two atoms or oxygen per molecule of carbon dioxide. Carbon has molecular weight of 12. Oxygen molecular weight is 16. Total 12+16+16= 44 11 grams/44 grams/mole=0.25 moles of carbon The grams of water and combustion of 7.5 grams are totally irrelevant. They are only given to possibly confuse you.

### How many tons of carbon dioxide are equivalent to one ton of carbon?

You must determine how many grams are in a tonne. You then must then use the molecular weight of carbon to determine the moles of carbon in that many grams (i.e. (grams C)/(M.W. of C)). As there is one mole of Carbon in each mole of carbon dioxide, then multiply the resulting moles of carbon by the molecular weight of CO2 and you will have your answer. OR... One metric ton (tonne) of of carbon…

### How many molecules of carbon dioxide are in 485 grams of carbon dioxide?

By experiment, a gram mole of any substance contains about 6.022 X 1023 molecules of the substance. The gram molecular mass of carbon dioxide, with the formula CO2, is about 44.01. Therefore 485 grams of carbon dioxide contains 485/44.01 or about 11.02 gram molecular masses. The formula for carbon dioxide shows that each molecule contains one carbon atom. Therefore, 11.02 moles of carbon dioxide contains 11.02 X 6.022 X 1023, or about 4.00 X 1024…

### How do you get the specific gravity of a mineral?

Fill a beaker with water, and weigh it. Weigh a sample of the mineral. That's the mass of the mineral. Put the sample in the beaker and weigh that. The weight of the water-filled beaker plus the weight of the mineral sample will be greater than the weight of the beaker with mineral sample and water. The difference is the weight of the displaced water, in grams. The volume of the mineral sample, in cubic…

### What gas is more dense than carbon dioxide?

Carbon dioxide has a mole weight of 44 grams. Nitrogen dioxide is 46 grams. Nitrogen trioxide is 62 grams. Sulfur dioxide is 64 grams. Chlorine is 71 grams. Sulfur trioxide is 80 grams. Krypton is 84 grams. Xenon is 131 grams. Bromine is 160 grams. Remember that all gases except column 18 (the nobles) couple up two atoms to a molecule. All the above are to the nearest whole gram. All gases occupy 22.4 liters…
