13 Water is 888 oxygen by mass What mass of water contains 320 g of oxygen A 36036 g B 3604 g C 360 g D 284 g E 2842 g F 28416 g class=

Respuesta :

Answer:

Option A. 36.036 g

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
