The weight of a flash drive is 3.5 grams. a) what is the weight of the flash drive in ounces ? b) a box containing 200 flash drives would weight how many pounds ?

1 gram = 0.035274 ounce

so 3.5 grams = 3.5*0.035274 =0.1234 ounce

also 1 gram = 0.0022 pounds

so 200 flash drives

200*3.5*0.0022 = 1.54 pounds
