Answer:
[CaCl₂] = 1.32 M
Explanation:
We know the volume of solution → 0.30 L
We know the mass of solute → 44 g of CaCl₂
Let's convert the mass of solute to moles.
44 g . 1 mol / 110.98 g = 0.396 moles
Molarity (mol/L) → 0.396 mol / 0.3 L = 1.32 M
<span>Thin, flattened, and typically curved bones, such as the ribs or sternum, form falt bones.
The two main functions of flat bones are protection or provide a large surface for musular attachment.
