What is the specific heat of silicon if the temperature of a 8.11 g sample of silicon is increased by 3.80 °C when 22.1 J of heat is added? Your answer should have 3 numbers after the decimal place, followed by a space, followed by J/gºC.​

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]

Estimate the molar mass of the gas that effuses at 1.6 times the effusion rate of carbon dioxide.

Concentrations expressed as a percent by mass are useful when the solute is a a. liquid b. gas c. solid
