How many moles of molecules are there in 16g oxygen
options
1)106
2)23
3)12
4)16
Oxygen is O2.
mols = grams/molar mass
O2 = 32 g/mol
so
16 g = 1/2 mol
thankyou :)
are you both teachers ??
To determine the number of moles of molecules in 16g of oxygen, we need to use the formula:
moles = mass (g) / molar mass (g/mol)
First, let's calculate the molar mass of oxygen (O). Oxygen (O) has an atomic mass of approximately 16 g/mol.
Next, we can substitute the given values into the formula:
moles = 16g / 16 g/mol
Simplifying the expression:
moles = 1 mol
Therefore, there is 1 mole of molecules in 16g of oxygen.
The correct option is 4) 16.
