We know for every 6.022 x 10^23 molecules, we have a mole of a substance, right? So if we have 3920molecules, we can use the above conversion factor to get: 3920 molecules CO2 x (1mol CO2/(6.022x10^23molecules CO2)) = 6.51 x 10^-21 moles CO2. There are three significant figures in this problem, from the 3929 molecules.

How many molecules of CO2 are present in 33.6g of CO2?
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 grams33.0 grams C / (44.0 grams) = .750 moles CO2
Determine the number of oxygen atoms present in 25.0g carbon dioxide?
Carbon Dioxide-CO2 To get molecules, we must convert grams to moles and moles to atoms using Avogadro's number. Molar mass of CO2= C:12.0g+O:16.0gx2=44.0g CO2 25.0g CO2 | 1 mol CO2 | 6.02x10 23 molecules CO2 ------------------------------------------------------------------- = 3.42x10 23 molecules CO2 1 | 44.0g CO2 | 1 mol CO2 Now to get the number of oxygen atoms. Since there are 3 atoms in CO2 and 2 of them are oxygen, we will divide by 3 (1.14x10 23) and multiply by 2 (2.28 x10 23) So the number of oxygen atoms in 25.0 grams of CO2 is 2.28x10 23 or 228 000 000 000 000 000 000 000
How many moles of CO2 molecules are present in 11g of carbon dioxide?
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.
How many moles of H2O are produced by the complete combustion of methane?
The complete combustion of any hydrocarbon, including methane, produces one water molecule for each two atoms of hydrogen in the hydrocarbon. The formula of methane is CH4; therefore, the complete combustion of one mole of methane produces two moles of H2O.
How many moles of lithium hydroxide are required to react with 20 mol of CO2?
40 moles of LiOH
Number of molecules in .75 moles of CO2?
0.75 moles CO2 x 6.02x10^23 molecules/mole = 4.5x10^23 molecules
What is the number of molecules in 2.00 moles of CO2?
12×1023 molecules
How molecules are in 2.4 moles of CO2?
1 mole CO2 = 6.022 x 1023 molecules 2.4mol CO2 x 6.022 x 1023 molecules CO2/1mol CO2 = 1.4 x 1024 molecules CO2
If a balloon contains 0.15 moles of CO2 gas. how many molecules of CO2 are in the balloon?
The number of molecules is 0,90332112855.10e23.
What Number of CO2 molecules in 0.0180 moles of CO2?
1 mol = 6.02 * 10^23 molecules 0.018 mol = 6.02 * 10^28 * 0.018 molecules 1.0836 * 10^27 molecules of CO2
Convert 5.3 times 10 raised to the 25 power molecules of CO2 to moles?
The answer is 88 moles.
How many carbon dioxide molecules are there in 3.74 moles of carbon dioxide?
3.74 moles CO2 (6.022 X 10^23/1mol CO2) = 2.25 X 10^24 molecules of carbon dioxide.
How many molecules are contained in 1.25 moles of carbon dioxide (CO2) and nbsp?
The number of molecules is 7,52767607125.10e23.
How many molecules in 0.4 moles of h20?
Each mole of a substance contains 6.022 E23 molecules or atoms of that substance. Four moles of H2O will contain 2.4088 E24 molecules.
How many moles of CO2 will be produced from 0.33 mol C3H8O in the reaction 2C3H8O plus 9O2 producing 6CO2 and 8H2O?
Given the balanced equation2C3H8O + 9O2 --> 6CO2 + 8H2OTo find the number of moles CO2 that will be produced from 0.33 mol C3H8O, we must convert from moles to moles (mol --> mol conversion).0.33 mol C3H8O * 6 molecules CO2 = 0.99 mol CO2---------- 2 molecules C3H8O
