Question

The production of sodium hydroxide in the United States during 1994 was 25.83 billion pounds.

a) How many grams of NaOH were produced during 1994?

b) The density of NaOH is 2.130 g/cm^3. How many cubic meters of NaOH were produced?

Answer 1

a) 11.716 x10^12 grams

b)2130000 grams per cubic meter

11.716x10^12 / 21300000 = 5500469 cubic meters <---  Answer.

You're so smart! ;-)

Answer 2

a) Since 1 pound = 453.59237 grams , 25.83 billion pounds = 11716290917100 gm

b) 1 cm³ = 10^(-6) m³ ,  11716290917100 gm means 5500606064366.197183099 cm³ i.e. 5500606.064366197183099 m³

Answer 3

25.83 billion pounds = 1.17162909 × 10^13 grams

(1 pound = 453.59237 grams

1 gram = 0.00220462262 pounds)

b) To convert from grams to mL (or cm^3), you've got to invert the density and multiply (it's easier):

(1.172 x 10^13 g) x (1 / 2.130 g/cm^3) = 5.500 x 10^12 cm^3 NaOH produced in 1994.
