Atomic Mass of C = 14g/mol
Atomic mass of O = 16g/mol
Molecular mass of CO2 = 12 + 2(16) = 44g/mol
mass = number of moles x molecular mass
mass = 3 mol x 44g/mol = 132g

How many grams are in 2 moles of carbon dioxide?
For this you need the atomic (molecular) mass of CO2. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. CO2=44.0 grams2.00 moles CO2 × (44.0 grams) = 88.0 grams CO2
How many grams of carbon dioxide are produced when 7.5 grams of sodium carbonate reacts with nitric acid?
First write the balance equation: Na2CO3 + 2HNO3 ==> 2NaNO3 + CO2 + H2O Next calculate moles of Na2CO3 used: 7.5 g x 1 mole/106 g = 0.071 moles Na2CO3 Then look at mole ratio of Na2CO3 to CO2 and see that it is 1 to 1 Thus, moles CO2 produced = 0.071 moles Finally, convert moles CO2 to grams of CO2: 0.071 moles x 44g/mole = 3.1 g (to 2 significant figures)
How many grams of CO2 are used when 6.5 g of O2 are produced?
1CO2 ==> 1O26.5 g O2 x 1 mol/32 g = 0.203 moles O2grams of CO2 = 0.203 moles x 44 g/mole = 8.9 grams
How many grams of carbon are required to prepare 10 L of CO2 at STP?
C + O2 ==> CO2At STP 1 mole CO2 = 22.4 L 10L x 1 mole/22.4 L = 0.446 moles CO2 needed 1 mole C = 1 mole CO2 Therefore you need 0.446 moles C grams C = 0.446 moles C x 12 g/mole = 5.36 grams = 5 g (to 1 significant figure)
How many C moles are in 167 moles CO2?
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms. So, 167 mole of CO2 has 167 mole of carbon atoms.
How many grams of CO2 are produced from 5 moles O2?
5.0 grams CO2 (1mol CO2/44.01g) = 0.11 moles CO2
How many moles are there in 6.5 grams of CO2?
6.5 grams CO2 divided by 44 grams CO2 per mole CO2 = 6.8 mole CO2 (Molar mass CO2 = 12 + 2*16 = 44 g/mol)
How many moles of co2 form when 58 grams of butane burn in oxygen?
The answer is 3,99 moles of carbon dioxide.
How many moles of CO2 form when 58 grams of butane C4H10 burn in oxygen?
The answer is 3,99 moles of carbon dioxide.
What is the number of moles of CO2 in 454 grams?
For this you need the atomic (molecular) mass of CO2. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. CO2=44.0 grams454 grams CO2 / (44.0 grams) = 10.3 moles CO2
How many grams are in 2 moles of carbon dioxide?
For this you need the atomic (molecular) mass of CO2. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel. CO2=44.0 grams2.00 moles CO2 × (44.0 grams) = 88.0 grams CO2
What is the mass of a half a mole of CO2?
1 mole CO2 has about 44 grams, so half a mole of CO2 equals 22 grams
How many grams of carbon dioxide are produced when 7.5 grams of sodium carbonate reacts with nitric acid?
First write the balance equation: Na2CO3 + 2HNO3 ==> 2NaNO3 + CO2 + H2O Next calculate moles of Na2CO3 used: 7.5 g x 1 mole/106 g = 0.071 moles Na2CO3 Then look at mole ratio of Na2CO3 to CO2 and see that it is 1 to 1 Thus, moles CO2 produced = 0.071 moles Finally, convert moles CO2 to grams of CO2: 0.071 moles x 44g/mole = 3.1 g (to 2 significant figures)
How many grams of CO2 are formed for every gram of CH4 that combusts?
The balanced equation for combustion of CH4 is CH4 + 2O2 ==> CO2 + 2H2OThus, one mole CH4 produces 1 mole CO21 g CH4 x 1 mole CH4/16 g = 0.0625 moles CH40.0625 moles CH4 ==> 0.0625 moles CO20.0625 moles CO2 x 44 g CO2/mole = 2.75 g CO2Thus, the answer would be that 1 grams of CH4 will produce 2.75 grams of CO2 after complete combustion.
Find the mass in grams of mol of CO2?
