evaporation systems allow for an endless source of water. you can grab cups of water straight from the sea or even a lake. the use of evaporation allows for you to drink water thats even healthier than getting it from a cloud and it will leave all of the bad parts that used to be in the water in the first container you pour into. this system is most useful in hot climates such as places near the equator.

Answer:

1.7\cdot 10^{15} g

Explanation:

Glucose reacts with oxygen do produce carbon dioxide and water:

C_6H_12O_6 (s) + 6 O_2 (g)\rightarrow 6 CO_2 (g) + 6 H_2O (l)

Given a daily mass of glucose:

m_1 = 5.0\cdot 10^2 g

Find moles of glucose:

n_1 = {5.0\cdot 10^2 g}{180.156 g/mol} = 2.775 mol

From stoichiometry of this equation, moles of carbon dioxide can be found by multiplying this amount by 6:

n_2 = 2.775 mol\cdot 6=16.65 mol

Convert this into mass using the molar mass of carbon dioxide:

m_2 = 16.65 mol\cdot 44.01 g/mol = 732.8 g

This is the mass of carbon dioxide per person per day. Multiply by the population and by the number of days to get the total mass:

732.8 \frac{g}{person\cdot day}\cdot 365 days\cdot 6.5\cdot 10^9 people = 1.7\cdot 10^{15} g
