4. An American football field is measured to be 100.00 yards long from goal line to goal line. To the correct number of significant figures, express this distance in nanometers (12 in 1 yard exactly; 2.54 cm-1 in exactly; 1 cm·10 m exactly: 1 nm-10 m exactly). 5. How many milliters of water (cm) do you have in a filled 3.50 cubic inch (in) container (2.54 cm -1 in exactly: 1 cm, 1 mL exactly)? 6. Several 100.00 ml samples of contaminated air contained an average of 14.7767 pg of arsenic. How many cubic meters of air would contain 0.500 kg of arsenic (1 pg 10 g exactly 1 kg 10 & exactly)? density of a material is calculated by its mass divided by its volume (D mass/volume). In the lab you weigh an empty graduated cylinder and find that its mass is 100.0848 grams. After you place several pellets of an unknown metal into the cylinder, you find that the mass of the cylinder with pellets is 115.6448 &. Now you add 25.00 ml of water to the cylinder and when you read the total volume in the cylinder, the result is
