Answer:

Explanation:
Glucose reacts with oxygen do produce carbon dioxide and water:

Given a daily mass of glucose:

Find moles of glucose:

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

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

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:

Three elements that are likely to have similar chemical and physical properties are
Answer : 50.69 mg of ascorbic acid does not meet the daily requirement.
Solution : Given,
Molar mass of Ascorbic acid = 176 g/mole
Moles of Ascorbic acid = 
Formula used :

or, 
Now put all the given values in this formula, we get the mass of ascorbic acid.

Conversion : 
As per question, a healthy adult’s daily requirement of vitamin C is 70-90 mg. But calculate mass of vitamin C is 50.69 mg. So, 50.69 mg of ascorbic acid does not meet the daily requirement.
