(a) 32 g of oxygen gas = 1 mole Then, 12g of oxygen gas = 12/32 mole = 0.375 mole (b) 18g of water = 1 mole Then, 20 g of water =...
Kelvin is an SI unit of temperature, where 0°C = 273 K (a) 300 K = 300 – 273 = 27°C (b) 573 K = 573 – 273 = 300°C
Kelvin is an SI unit of temperature, where 0°C = 273 K (a) 25°C = 25 + 273 = 298 K (b) 373°C = 373 + 273 = 646 K
