Answer:
Ron Clements and John Musker
Explanation:
- The density of the mineral fragment is
(20.47 g/cm3).
- Density can be regarded as<em> ratio of mass to the volume </em>of the object.
Density = (mass/ volume)
Given:
volume of mineral fragments= 2.57 cm3
mass = 52.6 g
density of the mineral fragment = (52.6/2.57)
= 20.47 g/cm3
- Therefore, density of the mineral fragment is (20.47 g/cm3)

Answer:
P(B) = 0.45 atm
Explanation:
Given data:
Total pressure = 1.30 atm
Partial pressure of A = 0.85 atm
Pressure of B = ?
Solution:
Total pressure = P(A) + P(B)
P(B) = Total pressure - P(A)
P(B) = 1.30 atm - 0.85 atm
P(B) = 0.45 atm
