Answer:
140.32mL per hour
Step-by-step explanation:
Rate of leakage of nitrogen ballon = 75 mL/h
Rate of leakage of helium ballon = x
Molar mass of nitrogen= Mn = 14
Molar mass of helium = Mh = 4
Effusion formula
Rate of effusion of helium/ Rate of effusion of nitrogen= √(Molar mass of nitrogen/Molar mass of helium)
Rate of effusion of helium = 75mL/h * √(14/4)
= 140.32mL/h
Answer:
36 ft³
Step-by-step explanation:
The volume of a rectangular prism is computed by multiplying the length, width, and height:
V = LWH = (9 ft)(1 ft)(4 ft) = 36 ft³
In exponential form: 10^2=3(x+5)
If we were to solve, x=85/3
Answer:
Step-by-step explanation:
the right choice is C
you use c^2=a^2+b^2
where the largest side is the hypotenuse
