How many moles of molecules are in 252 g of hydrogen nitrate (HNO3)?
Answer in units of mol
4 Mole
3.999
To find the number of moles of molecules in a given mass, we need to use the formula:
moles = mass / molar mass
First, let's calculate the molar mass of hydrogen nitrate (HNO3).
The molar mass can be found by adding up the atomic masses of all the individual elements in the compound.
The atomic masses of the elements are as follows:
Hydrogen (H) = 1 g/mol
Nitrogen (N) = 14 g/mol
Oxygen (O) = 16 g/mol
Now, let's calculate the molar mass of HNO3:
Molar mass = (1 * 1) + (14 * 1) + (16 * 3) = 1 + 14 + 48 = 63 g/mol
Next, we can use the formula to find the number of moles:
moles = 252 g / 63 g/mol = 4 moles
Therefore, there would be 4 moles of molecules in 252 g of hydrogen nitrate (HNO3).
