### NS is WRONG!!on CHEMISTRY QBANK 4 # 12

This one is under the newly added passages; I was following along on the explanation, which is pretty straight forward but they simply the mass to 2x10-7kg but when they apply the mass to the formula they use 20x10-7kg---the rest of the math is fine we end up with 4s as the answer but i think the correct math would have 0.4s which is answer choice A!! but NS highlights choice D as the correct one--> Please tell me i am right:)

Hi PoincareConjecture,

You are correct -- but there's another error yet, because 20 x 10^-6 = 2 x 10^-5, not 2 x 10^-7. We'll fix this ASAP. Thanks for pointing this out!
