True/False Questions.Write False next to the following statements if the statement if false. Write true next to thefollowing statements if the statement is false.1) Numbers are usually written so that the uncertainty is in the last reported digit.2) The decimal number 0.0000010 expressed in scientific notation is 1.0 × 106.3) The decimal number 0.0210 expressed in scientific notation is 2.10 × 10-2,4) The mass of an object, 4.55 x 10-3 g, expressed in decimal notation is 0.000455 g.5) Zeros located between two numbers are not significant.6). The imaginary decimal in the 24500 is located after the 5.7). Significant figures are important in chemistry because significant figures reflect the degree ofprecision of the instrument used.8) Zeros located after a number and after a decimal point are significant.9) Trailing zeros at the end of a number which does not have a decimal are not significant.10) The number 0.010100 has five significant figures.11) The number 4,450,000.0 has 3 significant figures.12) The number 7.20 x 103 contains three significant figures.13) When the temperature of an object is reported as 23.7°C, the actual temperature can be assumed to bebetween 23.6°C and 23.8°C.

In 1999, scientists discovered a new class of black holes with masses 100 to 10,000 times the mass of our sun, but occupying less space than our moon. Suppose that one of these black holes has a mass of 1×10^3 suns and a radius equal to one-half the radius of our moon. What is its density in grams per cubic centimeter? The mass of the sun is 2.0×10^30 kg and the radius of the moon is 2.16×10^3 mi (Volume of a sphere =4/3πr^3)
