For a very small number such as 6.674 x 10 the E notation representation is 6.674E-11 (or 6.674e-11). The metric system is called a decimal system because measurements of each type are related by factors of 10. If performing multiplication and division only, it is sufficient to do all calculations at once and apply the significant figures rules to the final result. e. Copper H = 5.0g * 24 C * 1 cal/g C 0000178704 00000 n Therefore, the answer needed to be rounded to the 0000063093 00000 n tenths place. SH = 1000 J / 19g * 74 C = 0.7 J.g C.
