I love Chemistry, but the quiz that we last week is so hard that our instructor told us to give the exact significant figures of the answer in a fixed answer.The question are:
1. From the sum of 23.90, 0.00034 and 123.234, subtract the product of 12.32 and 2.34.
2. What is the velocity of an automobile in meter per second that travels 12 kilometers east in three hours?
3. A rectangular piece of aluminum is 3.07 cm and 2.30 cm wide. a.) Find the area of the rectangle. B.) What is the area in square feet? c.) in square mile?
4. The mass of the planet Saturn ois 5.69 x 10 the the power of 26 kg. and its radius is 6.03 x 10 to the power of 7 m. a.) compute the average density of Saturn in kg/meter 3, using powers-of-ten notation and the correct number of significant figures. Express the density of Saturn in g/cm3. Will an object with the same average density of Saturn float in water?
