The given number of molecules is half of Avogadro's Number, which is defined as the number of molecules in one mole. Therefore, the given number of molecules is one-half of a mole. More exactly, 3.01/6.022 = 0.4998, but since the given number of significant digits is three in 3.01, this value rounds to 0.500. Therefore, the answer can be expressed as 0.500 moles.
If you are given the number of representative particles of a substance, and you need the number of moles of that substance, you must divide by Avogadro's constant, which is 6.02x1023. So: 3.75x1024/6.02x1023=0.623x101=6.23 moles.
Since a mole is 6.022x10-23 elementary entities, then I'd say to divide 3.754x10-23 by 6.022x10-23, resulting in 0.6233 moles of ethane.
3.4 X 10^23/6.022 X 10^23
= 0.56 moles
One mole has 6.022x10^23 atoms.So 0.5 mol has haif of it 3.011X10^23
0.5 mole CO2
b. 6.23 mol carbon dioxide
b. 6.23 mol carbon dioxide.
The number of molecules is 0,90332112855.10e23.
0.75 moles CO2 x 6.02x10^23 molecules/mole = 4.5x10^23 molecules
The number of molecules is 7,52767607125.10e23.
3.74 moles CO2 (6.022 X 10^23/1mol CO2) = 2.25 X 10^24 molecules of carbon dioxide.
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
The number of molecules is 0,90332112855.10e23.
0.75 moles CO2 x 6.02x10^23 molecules/mole = 4.5x10^23 molecules
The number of molecules is 7,52767607125.10e23.
12×1023 molecules
3.74 moles CO2 (6.022 X 10^23/1mol CO2) = 2.25 X 10^24 molecules of carbon dioxide.
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
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.
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
if you mean 10^22 O atoms, then this is how you do it: (8.16X10^22)/2=4.08X10^22 so there are 4.08X10^22 molecules, divided by 6.022X10^23(1 mole) is .06775, so there are that many moles of CO2. If you wanted to know how many moles of overall atoms there were, there's 4.08X10^22 molecules, 1 C in each so 4.08X10^22 C, and 8.16X10^22 O=1.224X10^23, and that's how many atoms, so that divided by 1 mole is (most accurate answer i can get you) .2032547326 moles of atoms so .2032547326 moles of atoms or .06775 moles of molecules/CO2
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.
1 mol = 6.02 * 10^23 molecules 0.018 mol = 6.02 * 10^28 * 0.018 molecules 1.0836 * 10^27 molecules of CO2
2.10 moles carbon dioxide (6.022 X 1023/1 mole CO2) = 1.26 X 1024 molecules of carbon dioxide ==============================
