3 bn tonnes of carbon dioxide ÷ 6.5 bn = (3 bn ÷ 6.5 bn) tonnes of carbon dioxide ≈ 0.462 tonnes of carbon dioxide = 462 kg of carbon dioxide.
Oxygen is the element that transformed Carbon Dioxide atmosphere a billion years ago to what you breathe.

B. 6.23 mol carbon dioxide
Global carbon dioxide emissions are 26 gigatonnes (26 billion tonnes) of carbon dioxide annually (2013).Carbon dioxide from all shipping is 4% to 5% of global emissions (1,300,000,000 (1.3 billion) tonnes).Ferries make up less than 1% of all shipping.So ferries probably emit around 13,000,000 (13 million) tonnes of carbon dioxide annually.
The molar mass of carbon dioxide is 44,01. For global warming see the link below.

Vehicle exhaust is mostly carbon dioxide, with a little water, carbon monoxide, hydrocarbons, and nitrogen oxides. This answer deals with the carbon dioxide content only.Sixteen percent (16%) of human carbon dioxide greenhouse gas emissions comes from road transport (cars, trucks and buses). Cars are responsible for about half of this (8%).Humans are responsible for around 35 billion tonnes of carbon dioxide emissions every year.Car emissions, 8% of that total, is around 2.8 billion tonnes of carbon dioxide (2,800,000,000).
3.75 X 1024 molecules carbon dioxide (1 mole CO2/6.022 X 1023) = 6.23 moles carbon dioxide ==================
