Atoms = 3.9 x 10. 24 atoms. 1 mole. 2. How many moles of argon are in a sample ... 6.02 x 10. 23 atoms. 3. How many moles are in 2.5g of lithium? 2.5 grams Li .
Answer:
3.53 g
Explanation:
To convert from atoms to moles, you need to know Avogadro's number. Avogadro's number (6.022 × 10²³) is how many atoms there are in one mole of a substance. Use this to convert.
(1.97 × 10²² atoms) ÷ (6.022 × 10²³ atoms/mol) = 0.0327 mol
Now that you have moles, use the molar mass to convert to grams.
(0.0327 mol) × (107.87 g/mol) = 3.53 g
<span>sulfurs electronic configuration is
1s2 2s2 2p6 3s2 3p4
so for the 3p sublevel
principal quantum no - 3
angulum quantum no - 1
magnetic quantum no - (-1) or 0 or (-1)
spin quantum no - (+1/2) or (-1/2)
so the quantum numbers will be
[ 3 , 1, -1 , +1/2 ] or [ 3 , 1, -1 , -1/2 ]
[ 3 , 1, 0 , +1/2 ] or [ 3 , 1, 0 , -1/2 ]
[ 3 , 1, 1 , +1/2 ] or [ 3 , 1, 1 , -1/2 ]

Yes..? I don’t understand what you’re trying to ask mate.
<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles.
65.39 g Zn ( 1 mol / 65.38 g ) ( </span>6.022 x 10^23 atoms / 1 mol ) = 6.023x10^23 atoms Zn
