Ba (OH) 2 Ba(OH) 2 is a string electrolyte, determine the concentration of each of the individual in a 0.400m Ba (OH)20.400m
1.2 g/mL, you find this by dividing 24.0g by 20.0 mL
The best quality answer I would say that it is cC
The correct answer is 2.70 × 10² g or 270 g.
It is given, that the density of a metal is 9.80 g/ml.
Let the mass of a sample of metal be x.
The sample of metal is dropped in 28.9 ml of water, due to which the volume of the water increases to 56.4 ml.
In order to calculate the mass of a metal, there is a need to use the formula, mass = density * volume
Mass = (9.80 g/ml) (56.4 ml - 28.9 ml)
= (9.80 g/ml) (27.5 ml)
= 2.70 × 10² g or 270 g
