All you have to do in convert two units. You need to know that there are 3600 seconds in an hour, and one kilometer is ~3,280.8399 feet. 3,280.8399 * 112 is equal to 367454.0688 feet per hour. Now divide it by 3600 to get it into seconds. That is equal to 102.07057466666667 feet per second. That's your answer.

Answer : The minimum amount of 6.9 M 
needed is, 2.0 L
Explanation :
The given chemical reaction is:
First we have to calculate the moles of 
Molar mass of = 2 g/mol
Now we have to calculate the moles of
From the balanced chemical reaction we conclude that,
As, 3 moles of produced from 3 moles of
So, 13.9 moles of produced from 13.9 moles of
Now we have to calculate the mass of
Thus, the minimum amount of 6.9 M needed is, 2.0 L
