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

If 1/2 costs 14p . Find the cost of 1 1/2 kg
Cost of 1 kg of sabu dhana = $2.60 Cost of 5.2 kg of sabu dhana = 5.2 x 2.60 = $13.52
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.
The cost would be 1.5 p.

Carbon: 105 kJ/mol = 105 (kJ/mol) / 0.012(kg/mol) = 8750 kJ/kg Carbon
Natural gas is essentially methane so the weight of 1 kgmole is 16 kg, this one mole contains 12 kg of carbon and occupies 22.4 m3. Therefore 1 m3 of gas contains 535 g of carbon CO2 has a molecular weight of 44 kg/kg mole, carbon is 12 kg/kg mole Therefore the weight cubic meter of carbon dioxcide is 535x44/12= 1964 g This is the amount emitted by burning 1 m3 of natural gas

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
