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
Your wight on the earth is greater because it has more gravitational pull whilebon the moon your weight is lower beacause of less gravitational pull.
Moles of Helium = 39.1 moles
ΔT = (38.08 – 0.08) ֯C = 38.00 ֯C
Q = nC ΔT = 39.1 * 20.8 J/ ֯C mol * 38.00 ֯C = 30904.64 J
W
= P * <span>ΔV = 1atm * (948 - 876) L =
122 atmL</span>
1atmL = 101.325 J
W = 122 * 101.325 J = 12361.65 J
ΔE = q + W = (30904.64 + 12361.65) J = 43266.29 J
Answer is 43266.29 J
