Answer:
The percent yield is 42.52%.
Explanation:
Theoretical yield of beryllium chloride = 12.7 g
Actual yield of the beryllium chloride = 5.4 g
The formula used for the percent yield will be :
Now put all the given values in this formula, we get:
The percent yield is 42.52%.
Answer:
It will take 140.76 seconds to swim 0.150 miles.
Explanation:
Distance covered by man by swimming for t time= d
d = 1500.0 miles
t = 14 minutes + 34.56 seconds
1 min = 60 seconds
t = 14 × 60 seconds + 34.56 seconds = 874.56 seconds
Speed of the man while swimming = S =
If the man swims 0.150 miles with the same speed ,then the time taken by him be T.
0.150 miles = 0.150 × 1609.34 m = 241.401 m
(1 mile= 1609.34 meters)
T = 140.76 seconds
It will take 140.76 seconds to swim 0.150 miles.
