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.
i actually have know idea and i want to find this out myself
Using the equation: Moles=Mass/Molar Mass
Moles=11/(12+16+16)
=11/44
=0.25 moles of CO2 molecules.
11.00/Atomic Weight x Na (Avagadro's number)
11 grams of carbon dioxide is the equivalent of 0,25 moles.
Moles of carbon dioxide = grams/amu of carbon dioxide. Moles = 19g/44amu Moles of carbon dioxide = .432
1.6*avagardo constant Avagardo constant=6.022*10^23
Four moles of sulfur dioxide would consist of how many molecules?
The same number of molecules implies the same number of moles.
0.1 moles There is one carbon and two oxygens 1 x 0.1 = 0.1
2.1 moles Carbon dioxide (6.022 X 1023/1 mole CO2) = 1.3 X 1024 molecules of carbon dioxide =============================
2,22 1023 molecules of carbon dioxide is equal to 0,368 moles.
Since each mole of carbon dioxide molecules contains two moles of oxygen atoms, as indicated by the formula CO2 for carbon dioxide, half a mole of carbon dioxide will have one mole of oxygen atoms.
2.10 moles carbon dioxide (6.022 X 1023/1 mole CO2) = 1.26 X 1024 molecules of carbon dioxide ==============================
7.30 moles carbon dioxide (6.022 X 10^23/1 mole CO2) = 4.40 X 10^24 molecules of carbon dioxide
Multiply by avagadro constant. It is equals to 6.022*1^23
3.74 moles CO2 (6.022 X 10^23/1mol CO2) = 2.25 X 10^24 molecules of carbon dioxide.
3.75 X 1024 molecules carbon dioxide (1 mole CO2/6.022 X 1023) = 6.23 moles carbon dioxide ==================
= 9403.41
6.23 mol carbon dioxide
6.32 mol carbon dioxide
B. 6.23 mol carbon dioxide
