molecular weight of carbon dioxide = 44u gram molecular weight of carbon dioxide = 44g given mass = 11g no. of moles = given mass divided by molar mass = 11 divided by 44 = 0.25moles.

Molecular weight of CO2 is about 44g (12g Carbon + 32g Oxygen *2 atoms Oxygen). So that means if you are presented with 44g CO2, that means there's 12g Carbon.

The only thing I can think of is that 32g of Oxygen is 2 mol and 12g of Carbon is 1mol so 44g of Carbon di-Oxide (CO2) would have exactly 32g of Oxygen and 12g of Carbon.

n=(1atm)(49L)/(0.0821)(273.15)=2.19 moles2.19 moles x 44g of CO2 =96.36g of CO22.19 moles x 100g of CaCO3= 219g of CaCO3

Use the equation; mass=moles*gramformulamass or m=n*gfm m=2*55.8 = 111.6g in two moles of Iron gfm or the molecular mass of a compound can be found by adding the Relative atomic masses of each element in the compound together. For example - Carbon dioxide CO2 The formula contains 1 Carbon atom and 2 Oxygen atoms (RAMs should be found in a datasheet/book or provided in the question. RAM = relative atomic mass) RAM Carbon = 12 RAM Oxygen = 16 gfm of CO2 = 12 + 32 = 44 or 1mole of CO2 = 44g

44g/mol

Carbon dioxide is CO2 and has a molar mass of 44g whereas propane is C3H8 and has a molar mass of 44g as well. Therefore, both are of equal mass

125 g of Zinc Carbonate is 1 mole and when it decomposes it forms 1 mole of Carbon Dioxide ZnCO3 = ZnO + CO2 1 mole of carbon dioxide has a mass of 44g 44g is the answer

Molecular weight of CO2 is about 44g (12g Carbon + 32g Oxygen *2 atoms Oxygen). So that means if you are presented with 44g CO2, that means there's 12g Carbon.

how much of co2 is released in by fossil fuels

Yes. CO2 has a weight of 44g/mol and O2 has a weight of 32g/mol.

0.88g of Carbon dioxide. For every 100g of limestone heated, 44g of CO2 and 56g of CaO are produced.

Multiply the value of 1 mole by 5. 44 g/mol x 5 mol Mole units cancel out, leaving 220g of CO2

44g of carbon dioxide is made with 100g of carbon dioxide. So, if 1 tonne is 1,000,000g, you need to multiply 44 by 1,000. Which makes 44,000, which is 0.044 tonnes.

C + O2 -------> CO2 12g of carbon produces 44g of carbon dioxide 1kg of carbon will produce 3-67kg of carbon dioxide

First you need to work out the balanced equation. 2C2H2 + 5O2 -----> 4CO2 + 2H2O From this we see that 2 moles of acetylene produces 4 moles of carbon dioxide. 1 mole of carbon dioxide is 12 + 16 + 16 = 44g (adding the mass numbers of the component elements). If 1 mole = 44g then 4 mole = 176g

One mole of 12C has a mass of 12.00000 grams (exactly, by definition).One mole of 13C has a mass of 13.00335 grams.One mole of 14C has a mass of 14.00324 grams.One mole of natural carbon - i.e. a sample with the ration of isotopes equal to that in nature - has a mass of 12.0107 grams.
