Answer to Question #140371 in General Chemistry for Skyler

Question

A 12 fl oz bottle of methanol is sold in a discount store as a gasoline additive to prevent freezing for $0.39. The density of methanol is 0.79g/cm^3 at room temperature. What is the price of the methanol per kilogram? What are the steps to solve?

Answer 1

1fl= 29.574ml

Therefore ,12fl= 354.888ml

$1ml = 1g=0.001kg$

Therefore, 354.888ml= 0.355kg

If 0.355kg are sold for $0.39, then 1kg will be sold for

(1/0.355)*0.39= $1.2
