8 is the answer . Since half a kg is 500g, 100 g would cost 1/5 as much. 1/5 of 40 is 8.

To find the cost of 250g at $4.80 per kg, we first convert 250g to kg by dividing by 1000 (since 1 kg = 1000g). This gives us 0.25 kg. Next, we multiply 0.25 kg by $4.80 to find the total cost, which is $1.20.
If 1/2 costs 14p . Find the cost of 1 1/2 kg
Approximately 50% of the weight of dry wood is carbon. Therefore, 1 kg of wood would contain around 0.5 kg (500 grams) of carbon.
If 1 kg of tomatoes costs 5 CHF, 0.1 kg will cost 1/10th of 5 CHF, so the cost will be 0.5 kg.
To convert 1 kg of carbon to carbon monoxide (CO), you need 1 kg of oxygen. This is because in the reaction of carbon with oxygen to form carbon monoxide, the ratio of carbon to oxygen is 1:1 by mass.
The weight of 1 kg of carbon dioxide (CO2) is approximately 1.87 kg when considering the atomic weights of carbon and oxygen in the molecule.
The cost would be 1.5 p.

LPG content can mostly considered as propane. Propane = C3H8 so the molecular mass is =3x12+1x8 = 44 Atomic weight Carbon = 12kg/kmol Hydrogen = 1 kg/kmol Each mole of Propane contain 3 mole of Carbon. Amount of carbon emitted per kg of LPG is (1kgPropane /44kg/kmol)x 3 molCarbon/molPropane x 12 kg/kmolCarbon =36/44 = 0.818 kg carbon release

To produce 100.0 kg of methanol, you would need 50.0 kg of carbon monoxide and 150.0 kg of hydrogen. This is because the reaction to produce methanol from carbon monoxide and hydrogen has a 1:3 ratio.
