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
Find the mass in grams of mol of CO2?
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 grams1.50 moles CO2 × (44.0 grams) = 66.0 grams 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 oxygen atoms are present in a 254 g sample of CO2?
Use dimensional analysis to solve this problem. First calculate the molecular mass of CO2. This is found by (use a periodic table) adding 12.011g of C to (15.999g x2) grams of Oxygen. Once you do that, you find out that 44.009g are in 1 mole of CO2. Now, simply by looking at the equation of CO2, we can tell that 2 moles of oxygen atoms are in 1 mole of Co2 (look at the subscript for Oxygen). Now, your dimensional analysis should look like this: 254g CO2 x 1 mole CO2/44.009g CO2 x 2 mole Oxygen/1 mole CO2 The answer is 11.5 moles of Oxygen in 254g of CO2.
What mass of CO2 is produced in the reaction of 4 moles of CH4 in excess O2?
Mass of 4 mole CO2 , this is 4 * (12 + 2*16) = 176 grams
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

What is the mass in grams of 4.73 moles of CO2?
Well considering the average atomic mass of 1 mole of C = 12.01115g and the average atomic mass of 1 mole of O = 15.9994g you add 2*15.9994 and 12.01115 to get a mole to mass conversion of 44.00995g per mole of CO2. You then 4.73 moles apply it to the conversion. 4.73 moles * 44.00995g/mole = 208.1670635g, rounded for three significant figures to 208. g. The answer: 208g of CO2.

How many moles of C do you have in the CO2?
1 mole of CO2 has 1 mole of carbon atoms and 2 moles of oxygen atoms.
What mass of CO2 is produced in the reaction of 4 moles of CH4 in excess O2?
Mass of 4 mole CO2 , this is 4 * (12 + 2*16) = 176 grams
How much does CO2 weigh?
Carbon dioxide has a molar mass of 44.0095 grams per mole. This means that one molecule of CO2 will have a mass of 7.308 E(-23) grams.
What mass of CO2 is produced when 50.0 g of C2 H4 reacts completely in C2 H4 plus 3 O2 equals 2 CO2 plus 2 H20?
C2H4 + 3O2 -> 2CO2 +2H2O 50.0 grams C2H4 (1 mole C2H4/28.052 grams)(2 mole CO2/1 mole C2H4)(44.01 grams/1 mole CO2) = 157 grams CO2 produced
How many CO2 moles comprise one mole of CO2?
6.02 ten to the power of 23
What is the mass of CO2?
how much of co2 is released in by fossil fuels
How many moles are in 42 grams of CO2?
just short of a mole. moles is mass/molar mass. mass is 42, molar mass is 44. 42/44
