For example, dimensional analysis could be used to determine the number of nickels in 3432.35 dollars.• To begin, write down the starting value, 3432.35 dollars. This can also be written as a fraction: nn delarn• Next, convert dollars to cents. This conversion involves a simple conversion factor: . Note that the "dollar" unit should appear on the bottom of this conversionI dellarfactor, since "dollars" appears on the top of the starting value.• Finally, convert cents to nickels. This conversion also involves a simple conversion factor. . This time "cents" should be on the bottom of the conversion factor,S cetasince it was on top of the previous conversion factor.• Combining these expressions gives us3432.35 dollars1 nickel5 centa100 centsI dollar• Finally, cancel units. Since dollars are divided by dollars, and cents are divided by cents, both of these units can be canceled. Multiplying through gives the final result:100 cents1 dottar3432.35 dollars1 nickel5 centa68, 647 nickels• To complete the calulation, multiply everything in the numerator and divide by everything in the denominator (or top and bottom, respectively).Practice with a sample problemYou wash dishes for a chemistry laboratory to make extra money for laundry.

The sodium D lines from a sodium lamp consist primarily of a doublet at 589.5 and 589.0 nm. Suppose we can obtain a grating with 500 lines/cm of any size we choose. How long (in cm) should the grating be required to separate the two sodium lines in the first order? Suppose the full length of the grating is illuminated.

||| = O MATTER Calculating volume by combining the volume of simple shapes A chemistry student in lab needs to fill a temperature-control tank with water. The tank measures 34.0 cm long by 17.0 cm wide by 14.0 cm deep. In addition, as shown in the sketch below, the student needs to allow 2.0 cm between the top of the tank and the top of the water, and a round-bottom flask with a diameter of 11.5 cm will be just barely submerged in the water. Calculate the volume of water in liters which the student needs. Round your answer to the nearest 0.01 L. Explanation Check 2 cm water X flask 21 OL m stv X 1/3 5 Kirste Ⓒ2023 McGraw Hill LLC.
