HORMONES ARE CHEMICAL SUBSTANCES SECRETED BY GLANDS
Answer:
11.35 g/cm³
Explanation:
If your rounding then 11.4. hope this helps :)
<span>when the number of moles Ca = mass of Ca / molar mass of Ca.
and we can get the molar mass of Ca, it is = 40 g/mol
and we have already the mass of Ca (given) = 9.8 g
so, by substitution: the moles Ca = 9.8 g / 40 g/mol
= 0.245 moles</span>
As the gas cools it condenses and becomes a liquid its atoms also become smaller
