PLEASE HEL ASA Assume a spoon holds 3.74 mL of water. The mass of 6.022 x 1023water molecules is 18.0 grams. The density of water is 1.00 g/mL. Assuming you could remove exactly 15 molecules of water every 0.47 seconds, how many years would it take to empty exactly 3 spoons of water? Use dimensional analysis to answer this question.
SHOW YOUR WORK PLEASE!

what are the choices?

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
