What is the mass of one mole of MgSO4?
If the MgSO4 is the only oxygen containing compound in the salt, there must be four moles of oxygen atoms, and the number of atoms in 4 moles is 4 multiplied by Avogadro's number or about 2.409 X 1024 atoms.
What is the percentage of oxygen by mass in water?
The percentage of oxygen by mass in water is approximately 88.8%.
What is the percentage mass of oxygen in morphine?
The chemical formula for morphine is C17H19NO3. To calculate the percentage mass of oxygen in morphine, determine the molar mass of oxygen in the formula (3(16 g/mol)) and divide by the molar mass of morphine (285 g/mol), then multiply by 100 to get the percentage. The percentage mass of oxygen in morphine is approximately 16.8%.
What is the percentage mass of oxygen in cocaine?
Cocaine is C17H21NO4 and has a molar mass of 303.353 g/mole. Mass of oxygen in cocaine is 4x16 = 64. So, % oxygen by mass is 64/303.353 (x100) = 21% (to 2 sig. figs)
How many moles are present in 1.64g of MgSO4?
To calculate the number of moles in 1.64g of MgSO4, you first need to determine the molar mass of MgSO4 which is 120.37 g/mol. Next, divide the given mass by the molar mass to get the number of moles. In this case, 1.64g ÷ 120.37 g/mol ≈ 0.014 moles of MgSO4.

What is the percentage of oxygen by mass in water?
The percentage of oxygen by mass in water is approximately 88.8%.
What is the percentage of oxygen in the Earth's atmosphere by mass?
The percentage of oxygen in the Earth's atmosphere by mass is approximately 21.
What is the percentage composition of oxygen in C7H15NO3?
The percentage of oxygen (in mass) is 29,776 %.
What element is larger H2o or MgSO4?
Neither H2O nor MgSO4 are elements. They are COMPOUNDS. In terms of volume occupied , MgSO4 is the larger.
What is the percentage mass of oxygen in morphine?
The chemical formula for morphine is C17H19NO3. To calculate the percentage mass of oxygen in morphine, determine the molar mass of oxygen in the formula (3(16 g/mol)) and divide by the molar mass of morphine (285 g/mol), then multiply by 100 to get the percentage. The percentage mass of oxygen in morphine is approximately 16.8%.
Do MgSO4 and NaCl weigh the same?
No Magnesium Sulfate (MgSO4) has a mass of 121, and Sodium Chloride (NaCl) has a mass of 59.
What is the percentage mass of oxygen in coedine?
Codeine : C18H21NO3Molecular Mass: 299Mass of oxygen present: 3 X 16 = 48Mass% of Oxygen : 48/299 * 100 = 16 %
What is the percentage mass of oxygen in cocaine?
Cocaine is C17H21NO4 and has a molar mass of 303.353 g/mole. Mass of oxygen in cocaine is 4x16 = 64. So, % oxygen by mass is 64/303.353 (x100) = 21% (to 2 sig. figs)

To calculate the number of moles in 1.64g of MgSO4, you first need to determine the molar mass of MgSO4 which is 120.37 g/mol. Next, divide the given mass by the molar mass to get the number of moles. In this case, 1.64g ÷ 120.37 g/mol ≈ 0.014 moles of MgSO4.
Oxygen is the most abundant element in?
As mass percentage oxygen is the most abundant.
How do you find the percent of oxygen by mass in a compound?
To find the percent of oxygen by mass in a compound, you need to know the molar mass of the compound and the molar mass of oxygen. Divide the molar mass of oxygen by the molar mass of the compound and multiply by 100 to get the percentage.
