Answer: The density would be p = 19.3 g/cm3 because
Explanation: because if you calculate density the formula would be d = <u>m</u>
v
so just use the values giving and you get the answer by plugging the 96.5 mass then 5 for the volume then divide it.
You take 80 g of Neon times 1 mol over the molar mass, 20.18 g/mol and multiply by Avogadro's number.

Answer: A) 3.5 mol/L</h3>
Explanation:
To determine the molarity, we have to find the number of moles in the volume given, and then extrapolate to find the number of moles that would be in 1 L.
<u>Determine the moles in the given volume</u>
moles of LiCl = mass ÷ molar mass
= 139.9 g ÷ 42.39 g/mol
= 3.30 mol
<u>Find the moles in 1 L</u>
Since 930 mL of LiCl = 3.30 mol
then 1000 mL of LiCl = (3.30 mol × 1000 mL/L) ÷ 930 mL
= 3.55 mol/L
