Answer:
The answer to your question is: 0.05 M
Explanation:
I'm not sure about the units umol, I think is units mol.
Data
MgF2 = 0.0191 mol
Volume = 400 ml
Molarity = moles / volume
Molarity = 0.0191 / 0.4 l
Molarity = 0.048 ≈ 0.05 M
Answer: D. all the empirical evidence available.
Explanation:
Answer:
The bolts will run out first, so these will limit how much product can be formed.
(option C is correct)
Explanation:
Step 1: Data given
Number of bolts = 5
Number of nuts = 12
ratio N:B = 2:1
Step 2
Since the ratio N:B is 2:1 we have 2 nuts for each bolt
When we have 2 bolts we have 4 nuts
When we have 3 bolts we have 6 nuts
When we have 4 bolts we have 8 nuts
When we have 5 bolts we have 10 nuts
We don't have more bolts, but there are still 2 nuts left. This means the bolts will run out first, so these will limit how much product can be formed.
(option C is correct)
F = (mass)(acceleration) = ma
m = 55 kg
Vi = 20 m/s
t = 0.5 s
Vf = 0 m/s (since she was put to rest)
a=(Vf-Vi)/t
a=(0-20)/5
a = 40 m/s^2 (decelerating)
F = ma = (55 kg)(40 m/s^2)
F = 2200 N
