Calculate the mass of a liquid with a density of 2.3 g/ml and a volume of 30 ml.

Hello there!

First you had to multiply by the density by the volume since D=M/V. Please make sure when your units has the same thing and it should be cancel it out.

2.3g/mL*30 mL= 69L is the right answer.

Hope this helps!

Thank you for posting your question at hereon

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
