Answer: 50.7 grams
Explanation:
To calculate the moles, we use the equation:
a) moles of
The balanced chemical equation is:
is the limiting reagent as it limits the formation of product and
is in excess.
According to stoichiometry :
2 moles of give = 1 mole of
Thus 0.220 moles of give=
of
Mass of
Thus 50.7 g of will be formed.
Answer:
Explanation:
Given parameters:
Number of breathe per minute = 15times
Volume of air per breath = 0.5L
Percentage of oxygen in air = 21%
Solution
There are 24 hours in a day.
60minutes makes a hour in a day,
I will breathe:
15 times x 60 x 24 = 21600 times in a day
The volume of air I will take in per day:
A breathe = 0.5L of air
21600breathe = 0.5 x 21600 = 10800L of air
Volume of oxygen I will breathe per day:
x 10800 = 2268L of oxygen
