Good morning and welcome to Chemistry!<\/p>\n\n\n\n

Today’s refresher is on density. Our old friend density is defined as a physical property of matter and can be described as the amount of mass per unit volume. Or, D=M\/V.<\/p>\n\n\n\n

If we use mass in grams (g) and volume in cubic centimeters (cm3<\/sup>) our density units will be in g\/cm3<\/sup> .<\/p>\n\n\n\n

If you draw the “Triangle of Science” with D=M\/V, all you have to remember is to put the mass in the top part of the triangle. The rest work out just fine.<\/p>\n\n\n\n

So, three quick questions for practice:<\/p>\n\n\n\n

  1. What is the density of a sample of metal if the volume is 12 cm3<\/sup> and its mass is 24 g?<\/strong><\/li>
  2. Tin has a density of 7.31 g\/cm3<\/sup>. If you have a 14.62 g sample of tin, what will be its volume?<\/strong><\/li>
  3. If you have a 100 cm3<\/sup> sample of tin what will be its mass?<\/strong><\/li><\/ol>\n\n\n\n

    Please show all your work on paper and send a picture of that paper to Mr. Brown in Remind. Include proper units in your final answer, of course.<\/p>\n\n\n\n

    Thank you.<\/p>\n\n\n\n

    Stay safe and stay Breezy!<\/p>\n\n\n\n
