At a certain temperature and pressure, one liter of CO2 gas weighs 1.15 g. What is the mass of one liter of N2 gas at the same t
lozanna [386]
Set up a proportion os V1/n1 = V2/n2. V is the volume, n is the amount in MOLES, not grams. Convert the CO_2 to moles, then solve and find that the amount of N_2 should be the same amount of moles. Then use the molar mass of N_2 (28.02 grams/mole) to convert that amount of moles into grams. That's your answer.

Lead has a density of 11.3 g/cm3. what is the volume of a 15.1 g block of lead?
Crank
Hey there:

density = 11.3 g/cm³

mass = 15,1 g

Therefore: 

D = m / V

11.3 = 15.1 / V

V = 15.1 / 11.3

V = 1.336 cm³
