Molar mass <span>CH2BrCH2Br = 188.0 g/mol
1 mole ---------- 188.0 g
</span>0.500 moles ----- ?
mass = 0.500 * 188.0 / 1
= 94.0 g
Answer C
hope this helps!

Answer:
<h2>3.0702 × 10²² molecules</h2>
Explanation:
The number of molecules potassium chloride can be found by using the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 0.051 × 6.02 × 10²³
We have the final answer as
<h3>3.0702 × 10²² molecules</h3>
Hope this helps you
