64 g of sulfur dioxide (so2) contains 32 g of oxygen. calculate how much sulfur it contains.
it contains 32g of sulfur.

describe what the answer to extension question 1 tells you about the mass of sulfur atoms compared to oxygen atoms.

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
