Question

calculate the number of oxygen atom present in 4.9g of glucose​

Answer 1

Answer:

Molar mass of H2SO4 = 98g

98g H2SO4 has 6.023×10^23 molecules

Therefore,49g H2SO4 has 3.0115×10^23 molecules

Again, 1 molecule H2SO4 has 4 oxygen atoms

Therefore,3.0115×10^23 molecules have 4×3.0115×10^23 oxygen atoms = 1.2046×10^24 oxygen atoms
