Perform the indicated arithmetic and express the answer using the correct number of signifigant figures..?
a] (956.1+0.01)X.02x22,000 = ?
b] (5.7 g -1.302g)/12.38mL = ?
c] 123cm x 2.045 cm x 100.0 cm = ?
Answer:
a] 400,000 - answer limited to 1 sig fig because of the 0.02 and the 0.01
b] 0.36 g/mL - 2 sig figs were the fewest used in the calculation
c] 25200 cm^3 - 100.0 is 4 sig figures so you are limited to 3 (123 has 3 sig figs).
a)...764.88
b)...0.45g/mL
c)...25,153cm³
