Water is composed of 11.2% hydrogen and 88.8% oxygen. what mass of water contains 50.0g of 0xygen?
g H2O x 0.888 = 50
To find the mass of water that contains 50.0g of oxygen, we can use the given percentage composition of water.
Step 1: Determine the mass of water that contains 100% oxygen.
Since oxygen makes up 88.8% of water, the mass of water that contains 100% oxygen can be calculated by dividing the mass of oxygen by its percentage in water:
Mass of water that contains 100% oxygen = (Mass of oxygen) / (Percentage of oxygen in water)
Mass of water that contains 100% oxygen = 50.0g / (88.8%)
Step 2: Calculate the mass of water.
To find the mass of water that contains 50.0 g of oxygen, we need to use the percentage composition of water:
Mass of water = (Mass of water that contains 100% oxygen) / (Percentage of water in 100% oxygen)
Mass of water = (50.0g / (88.8%)) / (11.2%)
Let's calculate this:
Mass of water = (50.0g / 0.888) / 0.112
Mass of water = 56.08 / 0.112
Mass of water = 500.7g (rounded to one decimal place)
Therefore, 500.7g of water contains 50.0g of oxygen.
