Number of moles :
500 / 180.16 => 2.775 moles
Volume = 0.72 L
M = n / V
M = 2.775 / 0.72
M = 3.85 M
hope this helps!
D. An organism stops taking in carbon when it dies.
Answer:
3.74 atmospheres
Explanation:
If the temperature is constant, then the formula is
V*P = V1 * P1
V = 22.6 L
P = 1.67 atm
V1 = 10.0 L
P1 = ??
=============
22.6 * 1.67 = 10 * P1
37.742 = 10 * P1
37.742/10 = P1
P1 = 3.742
Note there are 3 sig digs in each given, so the answer should be
P1 = 3.74 atmospheres
