Answer:
The molarity of a solution is "25 M".
Explanation:
The given values are:
Moles of solute,
= 12.5 g
Volume of solution,
= 500 mL
i.e.,
= 0.5 L
Now,
The molarity will be:
=
On substituting the values, we get
=
=
Time t=270 minutes=270/60=9/2 hours
distance s=63 miles
average speed v=s/t=63 ÷
=63×
=14 miles/hour
distance s=63 miles
average speed v=s/t=63 ÷
=63×
=14 miles/hour
