Answer:

2.35 x 10²³atoms

Explanation:

Given parameters:

Number of moles of Be = 0.39moles

Unknown:

Number of atoms = ?

Solution:

To solve this problem:

1 mole of a substance contains 6.02 x 10²³ atoms

0.39 mole of Be will contain 0.39 x 6.02 x 10²³ = 2.35 x 10²³atoms

How can I tell how many electrons in each energy level? When my question states "third sublevel" does this mean sublevel P?

nikitadnepr [17]

Sorry for the delay! My internet is a bit bad.
P is the third sublevel. Each sublevel (the angular momentum quantum number), has its own number:
<span>s = 1, p =3, d = 5, f = 7</span>
The number of electrons for each is:
s-2
p-6
d-10
f-14
It's easier to just memorize these numbers, but the equation for determining the sublevel number is 2n (n = the principal quantum number). The principal quantum number is based on the period the element is in.

Phosphorus-32 has a half-life of 14.3 days. how many grams of phosphorus-32 remain after 71.5 days if you start with 4.00 grams?

almond37 [142]

Answer : 0.125 g

Explanation : If you are calculating the half life of P-32 which has half life of 14.3 days and you want to calculate how many grams are remaining after 71.3 days if yo are starting with 4 g?

starting you can calculate the number of half life P-32 undergoes first,

which is n = 71.5 / 14.3 = 5 days.

now, to calculate the remaining mass,

$m_{remaining} = (\frac{initial mass}{2 X 2X 2X2 X2 } ) = (\frac{initial mass}{ 2^{5} } )$

= $= \frac{4 g }{ 2^{5} } = 0.125 g$
