Answer:
Partial pressure of oxygen = 23.38 kpa (Approx)
Explanation:
Given:
Amount of oxygen = 23.15%
Amount of nitrogen = 76.85%
Pressure (missing) = 101 kpa
Find:
Partial pressure of oxygen
Computation:
Partial pressure of oxygen = [Amount of oxygen x Pressure]/100
Partial pressure of oxygen = [23.15% x 101]/100
Partial pressure of oxygen = 23.38 kpa (Approx)
Answer:
43.18 gm
Explanation:
Heat of fusion of water at 0° C is 334 j/gm
then you have to heat the water to boiling point (100 C)
specific heat of water is 4.186 j/g-c
x = grams of water
x ( 334 + 4.186 (100) ) = 32500
x = 43.18 gm
