The relation between density, mass and volume is
1) to calculate = volume
given:
Density = 0.0915 g/ mL
mass = 17.7 grams
formula used:
Thus
Volume
Answer: 193.44 mL
2) the mass of sample will be
Answer: 7 g
Explanation:
dU=TdS-pdV (given)
To prove = 1) (at constant U)
2) (at constant V)
Solution: 1)
dU=TdS-PdV
Derivative of constant is zero.
Given that internal energy is ,U = constant
(hence proved)
Solution: 2)
dU=TdS-PdV
Differentiating with respect to dU, we get:
Derivative of constant is zero.
Given that volume is constant , V= constant
(hence proved)
