4. How much energy is required to vaporize 10.00 grams of water at
its boiling point?
(1) 100) (3) 2,260
(2) 260 3
(4) 22,600 )

distance, luminosity, brightness, radius, chemical composition, and temperature

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b
