Neon = app. 20.1795 g/mol
<span>Bromine = app. 79.904 g/mol </span>
<span>-----> 79.904 g/mol / 20.1795 g/mol = 3.96 (Close to 4) </span>
<span>Using Moles In 1000 g </span>
<span>1000 g / 20.1795 g/mol = app. 49.555 mol of Ne </span>
<span>1000 g / 79.904 g/mol = app. 12.515 mol of Br </span>
<span>-----> 49.555 mol / 12.515 mol = 3.96 (Close to 4) </span>
<span>Using Avogadro's Number </span>
<span>49.555 mol x 6.022x10^23 atoms = app. 2.984x10^25 atoms of Ne </span>
<span>12.515 mol x 6.022x10^23 atoms = app. 7.537x10^24 atoms of Br </span>
<span>-----> 2.984x10^25 / 7.537x10^24 = 3.96 (Close to 4) </span>
<span>So no matter how you look at it or calculate it, the answer is always the same. </span>
<span>I hope it helps!</span>
It is known as learned behavior. when you observe an animal, you learn from them. hope it helps:)
Answer:
0.06M
Explanation:
Using the formula as outlined in this question,
C1V1= C2V2
Where;
V1 = initial volume (Litres)
C1 = initial concentration (M)
V2 = final volume (Litres)
C2 = final concentration (M)
According to the information provided on NaOH in this question, V1 = 100mL = 100/1000 = 0.1 L, V2 = 1L, C1 = 0.6M, C2 = ?
C1V1= C2V2
0.6 × 0.1 = C2 × 1
0.06 = C2
C2 = 0.06M
The new concentration of NaOH is 0.06M.
