An empty flash has a mass of 123.4g. When the flask is filled with water, the mass is 211.6g. If 10.0g of zinc (d=7.14g/cm^3) is added to the flask filled with water (and the sides of the flask are dried from the displaced water), what is the new mass of the flask?

So here is a start.  Calculate the mass of water. 211-123 = mass of water.
 Use density to convert this mass to volume.  => ml of flask
Now you have the volume of the flask.  
Now you add 10 g of Zn.  Calculate the volume of that zinc, from density of Zn.
Water overflows.  Amount of water displaced = volume of zinc.  
COnvert that to g and you will get the mass of water displaced.  
Subtract this mass from the total mass before addition of Zinc (211)+10- mass of displaced water.
