Both mile and yard are units of distance thus they are inter convertible.
Distance covered in a marathon is 26.2 miles.
Since, 1 mile=1760 yards
Thus, distance can be converted into yards using the following conversion factor:
Thus, distance covered in marathon in yard will be:
Therefore, distance of the race is 46112 yards.
Answer:
The number of moles of NaCl contained in 0.5000 L of a 1.5 M (Molarity) solution is 0.75 moles.
Explanation:
Molar concentration is a measure of the concentration of a solute in a solution, be it some molecular, ionic, or atomic species.
Molarity M is the number of moles of solute that are dissolved in a given volume.
The Molarity of a solution is determined by the following expression:
Molarity is expressed in units .
In this case:
- Molarity= 1.5 M
- number of moles of solute= ?
- volume= 0.5 L
Reemplacing:
Solving:
number of moles of solute= 1.5 M* 0.5 L
number of moles of solute= 0.75
<u><em>The number of moles of NaCl contained in 0.5000 L of a 1.5 M (Molarity) solution is 0.75 moles.</em></u>
