The temperature is the independent variable. The independent variable is the variable that the researcher can control. And the dependent variable will change because of the change of independent variable. In this question, the student controls the temperature(independent variable) to see wether the gender(dependent variable) will change due to the temperature.
To solve for the mass of a substance is to simply get the

mass = density * volume
So calculating for mass:
mass = (2.76 g / cm^3) * 6 cm^3
mass = 16.56 g
