Question
As oarhy as you can, weigh (grams) and determine the volume (by water displacement, FIGURE 1.9) of a sample of basalt Add your data to the basalt density chart below. Calculate the density of your sample of basalt to tenths of a g/cm. Then determine the average density of basalt using all ten lines of sample data in the basalt density chart . As eactly as you can, weigh (grams) and determine the volume (by water displacement, FIGURE 1.9) of a sample of granite. Add your data to the granite density chart below.

Answer--
In that case you do know the sample density because without that this cant be calculated and you didnt share in the uploded question so if you have the density you can use the following formula to determine the smaple volume :
that is : D= m/v
well for finding the density or volume we use water displacement method .
water displacement method-
1- find the mass of the sustance using the balance.record the mass
2- fill a graduated cylinder large enough to hold the insoluble,irregular solid with water to a measured level .record the colume of water.
3- submerge the solid in the graduated cylinder's water ,tap the cylinder gently to allow trapped air bubbles to escape .record the volume of water and submerged object.
4-subtract the volume of water from the volume water with the submerged object.
5-divide the initial mass measurement by the voule to determine the density of the object.
And now you will get all the calculations.
