Answer:
0.906 gm/l
Explanation:
We know that molarity of the a solution is given by,
, where 'M' is the molarity, 'w' is the weight of the sample, 'm' is the molar mass, and 'v' is the volume of the solution.
Molarity of a solution tells us the concentration of the solute in the solvent.
Molar mass of KCl is = 74.55
Putting the values we get,
So the molarity of KCl solution is 0.906 gm/l.
Answer:
Density = 0.17 g/L
Explanation:
It is given that,
Volume of the inflated balloon filled with Helium,
Mass, m = 374 g
We need to find the density of helium. It is equal to its mass per unit volume. It can be given by :
d =m/V
So, the density of helium in the balloon is 0.17 g/L.
it will get warm or spread out into the water or
