Answer:
2.52kg
Explanation:
80mm = 8 cm
0.15m = 15 cm
volume of the container = 10m × 8cm × 15cm
= 1200 cubic centimetres
mass = density × volume
= 2.1 × 1200
= 2520g
2520/ 1000
= 2.52kilograms

if the same solution would be equal:
=> 0.5 grams of Sodium chloride dissolved in 0.05 liters solution
=> 0.5 moles of sodium chloride dissolved in 0.05 liters solution
The answer is NO. They are not equal because 0.5 grams of sodium chloride is equivalent
to 10 moles of sodium chloride which makes 0.5 grams of sodium chloride mixed
with 0.05 liters of solution more concentrated than 0.5 moles of sodium
chloride dissolved in 0.05 liters of solution.
