What is the mass of 3moles of lithium?
1 mole of lithium has a weight of 7g so, 3 moles weigh 7 x 3 21g
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.
What is the mass percent of oxygen in the compound?
To determine the mass percent of oxygen in a compound, you would calculate the mass of oxygen in the compound and then divide it by the total mass of the compound, before multiplying by 100. The formula is: (mass of oxygen in compound / total mass of compound) x 100%.
What is the percent by mass of oxygen in propanal CH3CH2CHO?
To find the percent by mass of oxygen in propanal (CH3CH2CHO), calculate the molar mass of oxygen (O) and the molar mass of the entire compound. Then divide the molar mass of oxygen by the molar mass of the entire compound and multiply by 100 to get the percentage. In this case, the percent by mass of oxygen in propanal is around 47.3%.
What is the percentage mass of oxygen in MgSO4?
The molar mass of MgSO4 is 120.37 g/mol. The molar mass of oxygen is 16.00 g/mol. To find the percentage mass of oxygen in MgSO4, we divide the molar mass of oxygen by the molar mass of MgSO4 and multiply by 100 to get 47.27%.

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)
What is the atomic mass of o?
The atomic mass of oxygen (O) is approximately 16 atomic mass units.
What is the mass percent of oxygen (O) in SO2?
(16.0g + 16.0g)/(32.1g + 16.0g + 16.0g) x 100 %
Is an oxygen atom have twice the mass of a sulphur atom?
No, an oxygen atom does not have twice the mass of a sulfur atom. An oxygen atom has a mass of approximately 16 atomic mass units (amu), while a sulfur atom has a mass of approximately 32 amu. Therefore, a sulfur atom has twice the mass of an oxygen atom.
