Calculate the number of C, H and O atoms in 1.75 g squaric acid. :)
1.75 g/molar mass = moles.
#atoms C x moles x 6.022E23 = ??
Same for H and O.
To calculate the number of C, H, and O atoms in a compound, you first need to know the molecular formula of the compound. The molecular formula for squaric acid is C4H2O4.
To determine the number of atoms, you will need to use Avogadro's number. Avogadro's number, denoted as NA, is approximately 6.022 x 10^23 atoms per mole.
Step 1: Calculate the molar mass of squaric acid
The molar mass of squaric acid (C4H2O4) = (4 x atomic mass of C) + (2 x atomic mass of H) + (4 x atomic mass of O)
Atomic masses:
C (Carbon) = 12.01 g/mol
H (Hydrogen) = 1.008 g/mol
O (Oxygen) = 16.00 g/mol
Molar mass of squaric acid = (4 x 12.01 g/mol) + (2 x 1.008 g/mol) + (4 x 16.00 g/mol)
Step 2: Calculate the number of moles of squaric acid
moles = mass / molar mass
Given that the mass is 1.75 g, you can substitute it into the equation:
moles = 1.75 g / (molar mass obtained in Step 1)
Step 3: Calculate the number of atoms
To calculate the number of atoms, multiply the number of moles by Avogadro's number (NA).
number of atoms = moles x Avogadro's number
Simply substitute the value from Step 2 into the equation:
number of atoms = moles x 6.022 x 10^23 atoms/mol
Using these calculations, you will be able to determine the number of C, H, and O atoms in 1.75 g of squaric acid.
