Answer:
Volume occupied by 55.5 moles of water gas at STP = 1240 Liters.
Explanation:
1st keep in mind that 'volume' in the context of problems like this apply only to the gas phase form of the substance. Water in solid form (ice) or liquid form (liquid water) do not apply. Volume in this case is referred to as 'molar volume' and is a gas occupying 22.4 liters at STP conditions (0°C, 1Atm).
So, if 1 molar volume of water gas (steam) occupies 22.4 Liters at STP, then 55.5 moles of water gas occupies 22.4 Liters/mole x 55.5 moles = 1243.2 Liters, or 1240 Liters (3 sig. figs.). :-)
Answer:
2.67761514 moles
Explanation:
0.075kg equates to 75g.
This means that the car emits 75g of CO per km.
dividing 75g by the molar mass of CO (28.01g/mol) we get 2.67761514 moles
i think so.
i learned this recently and my textbook says that neutrons and protons are in the nucleus and electrons orbit around the nucleus. :)
i hope i was able to help
