Calculate the specific heat capacity of this sample of mercury if The amount of energy required to heat 2.00 grams Hg from 50 degrees C to 85 degrees C is 9.87 J.
A sample of water of 18 g absorbs 561.2 J of heat calculate what is the final temperature of the water if the initial temperature of the water was measured to be 9.0 degrees C. (Specific heat capacity of water = 4.184 J/g C)
Garlic smell is easily noticable due to the compound that is responsible for this is Allicin , when we analysed this compaound and find out molecular formula of molar mass= 486 grams
Application of Avogadro's law - To evaluate the volume of a gas using Avogadro's Law.
calculate the difference in mass that is hold by a 500.0mL flask at a temperature of 0.0°C from that at temperature of 20.0 °C? (you can assume the volume of the sample at 0.0 °C temperature =volume of the sample at 20.0°C)
