Two.
3KNO3, so 9 oxygen atoms.
Two, HCOOH the formic acid.
Carbon, Hydrogen, Oxygen and Nitrogen.
It depends on how many hydrogens are there and how many oxygen atoms there are.
Copper(II) nitrate has six oxygen atoms.
3KNO3, so 9 oxygen atoms.
6 carbon, 10 hydrogen and 5 oxygen atoms
The number of atoms is indicated by coefficients.
[ 4.0(g) / 16(g/mol) ] * 6.0*1023= 1.5*1023 O-atoms
4 oxygen atoms are present
Glycerol C3H8O3 has three Carbon, eight Hydrogen and three Oxygen.
Two, HCOOH the formic acid.
Carbon, Hydrogen, Oxygen and Nitrogen.
It depends on how many hydrogens are there and how many oxygen atoms there are.
The chemical formula for ozone is O3 - three oxygen atoms.
Amount of oxygen = 5.2/32.0 = 0.163mol Number of oxygen molecules = 0.163 x 6.02 x 1023 = 9.78 x 1022 Number of oxygen atoms = 2 x 9.78 x 1022 = 1.96 x 1023
Copper(II) nitrate has six oxygen atoms.
