Question
1.49
Which of the these uncertain values has the largest number of significant figures? 1/545; 1/6.4 times 10^-3; 1/6.50; 1/1.346 times 10^2 Which of these uncertain values have four significant figure 0.0592; 0.08206; 8.314; 5420; 5.4 times 10^3 Which of these uncertain values have only three significant figures? 7.02; 6.452; 6.02 times 10^23; 302; Perform each of the following calculations and answer with the correct number of significant figure the highlighted values are exact): 0.6274 times 1.00 times 10^3/[2.205 times (2.54)^3] = 6 times 10^-18 times (1.00 times 10^3) times 12 = (4.00 times 58.69)/(6.02 times 10^23 times 6.84) = [(26.0 times 60.0)/43.53]/(1.000 times 10^4) = Perform each of the following calculations, answer with the correct number.
Explanation / Answer
a. 0.6274*1.00*10^3 /32.205*(2.54)^3
1.19 >>>> answer
b. 6*10-18 * (1.00*103 ) *12 = 3.6*10-14
c. (4.00*58.69)/(6.023*10^23 * 6.84)
= 5.69*10-23 >>>> answer
d. (26.0*60.0)/43.53/(1.000*10^4 ) = 0.00358 >>>> answer
