Part 1: a sample of silver (ag) has a mass of 31.78 g. a.) what is the molar mass of silver? b.) how many moles of silver are in this particular 31.78 g sample? c.) how many atoms of silver are in this same sample?show work! you!

Strong conductivity of plasma allows it to act and react as and

Calculate the number of kilojoules to warm 125 g of iron from 23.5°c to 78.0°c.

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)]
