Helium has a density of 1.79 x 10-4 g/mL at standard temperature and pressure. A balloon has a volume of 6.3 liters. Calculate the mass of helium that it would take to fill the balloon. Be sure to follow significant figure rules when calculating the answer

Question

abb0t · Answer

You'll want to multiply by 6.3 liters to get grams.

joannablackwelder · Answer

But first you will need to make your units of volume the same.
mass=density*volume
where the units of volume cancel out

Make sense, @kelseykimble ?

(6.3 L) x (1000 mL/L) x (1.79 x 10^-4 g/mL) = 1.2 g
