24use the photosynthes eqn and use mole concept
1 gm of dry green algae absorbs 4.7 x 10 to the power -3 mole of CO2 per hour by photosynthesis as starch,how long would it take for the algae to double their own weight?????

11See 44g is 1 moles of CO2
Then 4.7 * 10-3moles = xg
xg is added to algae every hour therefore for 1 g how much time
t = 1/x
x = 4.7 * 10-3/44
x = 1.068 * 10-4
t = 1/1.068 * 10-4
t = 9.36 *1000
t = 9360 hours
