What is the mass of 0.60 moles of Al?

45 × 1023 grams
24 × 1023 grams
16 grams
12 grams

It helps to map out how you will navigate through your unit analysis problem before setting it up.  

You are given moles and need grams.  What can be used as a conversion factor from moles to grams?  Molar mass.  We are working with aluminum, so we will need the molar mass of aluminum.  My Periodic Table tells me the molar mass of aluminum is approximately 27 g/mol.  Now we are ready to set up the unit analysis.

Moles must go on the bottom so that they cancel.  Notice how our number of significant figures is 2, so the answer must round to 16 g Al.

16 grams

alienation, transformation, consumption, and the relativity of truth.

you can choose any one of these, they are all important themes.

these themes reflect the distinct sensibilities of both the modernist and postmodern aesthetic movements. (from google, you should paraphrase)

hope this !
