Answer:
Option A. 36.036 g
Step-by-step explanation:
From the question given above, the following data were obtained:
Percentage of oxygen in water = 88.8%
Mass of oxygen = 32 g
Mass of water =..?
Mass of water that contains 32 g of oxygen can be obtained as follow:
Percentage of oxygen = mass oxygen /mass of water × 100
88.8% = 32/mass of water
88.8 /100 = 32/mass of water
Cross multiply
88.8 × mass of water = 100 × 32
88.8 × mass of water = 3200
Divide both side by 88.8
Mass of water = 3200/88.8
Mass of water = 36.036 g
Therefore, the mass of the water that contains 32 g of oxygen is 36.036 g
