... cylinder up to 50mL mark is obtained by first finding the volume; (V = ?r²h). Pi is 3.1416, and the radius is determined by dividing the diameter of the 100mL graduated cylinder (2.5cm) in half, or 1.25cm. The height of the 50mL mark is 9.5cm. The formula is V = 3.1416 * (2.5cm)² * 9.5cm, or 46.63mL³. 3.) The experimental error looks like this: (50.00 - 46.63mL³) / (50.00) * 100 = 6.74% error 4.) Mass of water is determined by subtracting the mass of the 25mL cylinder from the measured mass of the 25mL cylinder and water, or: 65.1g - 50.8g = 14.3g The mass of the water according to the density formula is D = M / V, or 0.997569= m / 16mL, or 15.961g. The experimental error looks like this: (14.3g - 15.961g) / (14.3g) * 100 = 11.6% error. 5.) The volume of the metal is obtained by subtracting the volume ...
