And here's the flask
A flask has a mass of 54.12 g when empty and 180.27 g when filled with water. the density at 22.1°C is 0.997747 g/ml. when the same flask is filled with an unknown liquid, the total mass of the flask and liquid is 142.145g. What is the density of the unknown liquid?
so far I have:
Mass= 180.27g - 54.12g
Mass of unknown liquid= 142.145g - 54.12g
and yeah...that's all I have......
