How many grams of ammonia would be produced by the decomposition of 16.93 mlof hydrazine? (the density of hydrazine is 1.021g/ml)

Give one example of a pure (exact) number and of an estimated (measured) number.

What is the temperature in kelvin of a gas if it is allowed to expand from 1.50 l to 4.50 l? the initial temperature is 10.0°c and pressure is constant throughout the change. which equation should you use? t2= v2/v1 t1 what is the final temperature? ⇒ 849 k these are the answers.
