Answer:
Density,
Explanation:
The attached figure shows a 38.6 kg marble slab. The dimensions of the marble slab is 23 cm × 17 cm × 4 cm
Density = mass/volume
Volume of a cuboid shape is equal to, V = 23 cm × 17 cm × 4 cm
V = 1564 cm³
Density,
or
So, the density of the marble slab is .
Answer:
Explanation:
Hello,
In this case, since the molarity is computed by:
Whereas the solute is the hydrochloric acid, we compute the corresponding moles with its molar mass (36.45 g/mol):
Next, since the solution contains both HCl and water, we compute the volume in liters by using its density:
Therefore, the molarity turns out:
