An empty container with a volume of 160.0 cm3 is weighed and found to have a mass of 74.9 g. The container is filled with a liquid and reweighed. The mass of the container and the liquid is 190.1 g. What is the density of the liquid to the appropriate number of significant figures?

the answer is   c.) 1575 j.

explanation:

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
