An aluminum sample has a mass of 80.1 g and a density of 2.70g/cm3 . According to the date to what number of significant figures should the calculate volume of the aluminum sample be expressed?

3 Sig figs because both measurements have three sig figs. In a lab setting, you would round to your least precise measurement. So its useless to use a meter stick and a high precision scale to take measurement because you have to use the amount of Sig figs for your least precise tool

80.1 g (1 cm^(3)/ 2.70 g)= 29.666666... cm^(3).

The calculated volume should have 3 significant figures, so the final answer is 2.9710^(1) cm^(3)

Hope this helps~
