Suppose that you find in a reference book that the volume of all the oceans is 1.4 x 10° km. To find the mass, you can use the density of water, also found in this reference book, but first you must convert the volume to cubic meters. What is this volume in cubic meters?

1.30 The largest computers now include disk storage space measured in petabytes. How many bytes are in a petabyte? (Recall that in computer terminology, the prefix is only “close” to the value it designates in the metric system.)
A student checked the accuracy of two standard top-loading balances by testing them with a standard 5.000-g mass. The results were as follows: Balance 1: 4.99 g, 5.04 g, 5.03 g, 5.01 g Balance 2: 4.97 g, 4.99 g, 4.95 g, 4.96 g Calculate the average values for balances 1 and 2 and calculate the percent error for each. Which balance is more accurate?

How many molecules are contained in 5.00 microliters of methanol (CH4O)? The density of methanol is 0.792 g/mL. Use these atomic masses: C = 12.011 amu; H = 1.008 amu; O = 15.999 amu. Input your result in scientific notation using the format with the lower case e representing the x10. For example, in this format the number 1.234x109 would be expressed as 1.234e9. The number 1.234x10-9 would be expressed as 1.234e-9 Not these answers 0.1569 1.23 0.1569 0.0001

A sample of gold alloy has a mass of 9.3 kg. It is determined that 0.6 kg of the alloy is actually made up of copper and zinc, with the remainder being gold. Calculate the percentage of this gold in the alloy? Express your answer to the nearest percentage (nearest ones place). Hint: calculate the mass in grams of the gold in the alloy, divide by the whole mass of the alloy, and multiply by 100%. Round your answer to two significant figures. (I had to alter the wording of this question since it wasn't calculating significant figures properly, so if you got it wrong because of significant figures you can assume you probably actually got it correct.)
#1 Solve the problem, please read directions carefully. Thumbs up if you do it correctly. Be sure to round your answer to the correct number of significant figures. Please see the example I provided in the screenshot. The answer should be in this type of format with this unit symbol -- (example: 0.0057 kJ/K)
