of the truck slid forward.
Answer:
14 mol O₂
Explanation:
The reaction between CO and O₂ is the following:
CO + O₂ → CO₂
We balance the equation with a coefficient 2 in CO and CO₂ to obtain the same number of O atoms:
2CO + O₂ → 2CO₂
As we can see from the balanced equation, 1 mol of O₂ is required to react with 2 moles of CO. Thus, the conversion factor is 1 mol of O₂/2 mol CO. We multiply the moles of CO by the conversion factor to calculate the moles of O₂ that are required:
28 mol CO x 1 mol of O₂/2 mol CO = 14 mol O₂
Answer:
600,000
Explanation:
In order to convert meters or metre to millimeter or millimetre, you must multiply the meter/metre by 1000. (Some countries say meter and others say metre.) Hope it helps! <3
Explanation:
Volume of the stock solution is
= ?
Initial concentration of ampicillin is
= 100 mg/ml
Final volume (
) = 30 ml
Final concentration of ampicillin (
) = 25 mg/ml
Therefore, calculate the volume of given stock as follows.
= 
Now, putting the given values into the above formula as follows.
= 
=
= 7.5 ml
Now, we will calculate the volume of water added into it as follows.
Volume of water added = 
= 30 ml - 7.5 ml
= 22.5 ml
Thus, we can conclude that required solution is 22.5 ml of deionized water.
