Question

Calculate the atomic and mass ratio of H2O and CO2​

Answer 1

Answer:

calculate the atomic and mass ratio of h20 and co2

Answer 2

i) Molecular mass of H2O = 2 (1.008 amu) + 16.00 amu = 18.016 amu. (ii) Molecular mass of CO2 = 12.01 amu + 2 ×16.00 amu = 44.01 amu.

Convert the mass of each element to moles of each element using the atomic masses. Find the ratio or the moles of each element by dividing the number of moles of each by the smallest number of moles. There are fewer moles of oxygen than any other element, so we will assume one mole of oxygen to establish the ratios.
