Answer:
0.779 moles.
Explanation:
Mass of chlorine/number of moles = molar mass of chlorine.
Molar mass of chlorine = (35.5*2)
= 71 g/mol.
Mass = 55.3 g of chlorine.
Number of moles = 55.3/71
= 0.779 moles.

I think the answer is letter B.
Answer:
<h3>The answer is 82.86 cm³</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula

From the question
mass of wood = 44 g
density = 0.531 g/cm³
It's volume is

We have the final answer as
<h3>82.86 cm³</h3>
