To make 200 mL of 150 mM NaCl, weigh ___ grams of NaCl, place in a graduated cylinder, and add water to make the total volume ___ mL. To make 500 mL of 200 mM NaCl, weigh ___ grams of NaCl, place it in a graduated cylinder, and add water to make the total volume ___ m...
solid objects do not have regular shapes. This technique is based on the principle that any solid that does not dissolve or react with the liquid it is placed in will displace its own volume when submerged. The weighed solid is added to a known volume of water in a graduated cylinder and...
Place the solid into the graduated cylinder. Step 4 Measure the amount of water in the graduated cylinder. Step 5 Subtract the value in Step 2 from Step 4. The difference is the solid's volume. Step 6 Determine the solid's density using the appropriate table found in the Resource section...
