Iridium is one of the densest metals. How many times heavier would a standard pencil be if it were made out of iridium instead of wood? NOTE: The density of Iridium is 22.56 g/$$cm3 A standard pencil has a mass of 5.438 g A standard pencil is roughly 19 cm long with an 8 mm diameter

your answer would be 10x - 1

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
