Zoe has 25 grams of water (c = 4. 186 joules over grams times degrees Celsius) at 10°C, which she mixes with 12 grams of water at 30°C. Assume that no heat is lost to the surroundings. What is the final temperature of the two liquids? The answer is expressed to the nearest whole number. –47°C –8°C 3°C 16°C.

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
