The correct answer for this will be
atomic
mass
Answer:
there'd be 2 electrons
Explanation:
number of electrons= number of protons
Answer:
1 is B, 2 is B a cold front
Explanation:
In order for a front to form, two air masses have to collide, and for 2 a cold front is represented by a red ljine with half circles
Average atomic mass also considers the mass of the isotope of that element found in nature
Answer:
a) atoms Pb = 4.3595 E22 amu
b) g = ( 6.022 E23 amu ) × ( Mw )
Explanation:
sample:
∴ m = 15.00 g
a) atoms Pb = ?
⇒ atoms Pb = (15.00g Pb)(mol Pb/207.2 g)(6.022 E23 amu/mol)
⇒ atoms Pb = 4.3595 E22 amu
b) relationship:
∴ 1 mol (n) ≡ 6.022 E23 amu......(1)
∴ mass (g) ≡ (Mw)×(n)
⇒ n = g / Mw..........(2)
∴ Mw: molecular weight
(1) = (2):
⇒ g / Mw ≡ 6.022 E23 amu
⇒ g ≡ ( 6.022 E23 amu ) × ( Mw )
