The formula is density = mass / Volume
density = ?
mass = 21 g
Volume = 9 mL
d = m / V
d = 21 g / 9 mL
d = 2.3 g/mL
Hope this help!

sent a picture of the work. hope you see it
Answer:
121.63 g/mol
Explanation:
Sr(OH) 2 = Strontium Hydroxide
Answer:
about 10 pounds
Explanation:
your mass doesn't change but weight changes (due to gravity)
<span>Solubility product constant (Ksp) is </span>applied to the saturated ionic solutions<span> which are in equilibrium with its
solid form. The solid is partially dissociated into its ions.</span><span>
For the BaF, the dissociation as follows;
BaF</span>₂(s) ⇄ Ba²⁺(aq)
+ 2F⁻(aq)
<span>
Hence,
Ksp = [Ba</span>²⁺(aq)] [F⁻(aq)]²
