Answer:
approximately 83.33
Explanation:
The formula for the area of a right square pyramid is:
V= a^2(h/3)
a= base edge
h= height
The height is 10 inches, and the base edge is 5 inches. Plug it in to the formula:
V= 5^2 (10/3)
V= 25 (10/3)
V= 83.33 in^3
Answer:
2.01
Explanation:
The effusion is the passage of the molecules by a small hole by a difference of pressure. By Graham's Law, the rate of the effusion is inversely proportional to the square of the molar mass of the compound. Thus,
rateHF/rateHBr = √MHBr /√MHF
MHBr = 81 g/mol
MHF = 20 g/mol
rateHF/rateHBr = √81/√20
rateHF/rateHBr = 2.01
