Question

If 10 mL of sulfuric acid weighs 18g and an equal volume of water weighs 10g, the density of the acid is _______________ and the specific gravity of the acid is _______________.

a) 1.8 g/cm³; 1.0
b) 0.8 g/cm³; 1.8
c) 1.0 g/cm³; 0.8
d) 1.8 g/cm³; 0.8

Answer 1

The density of sulfuric acid is 1.8 g/cm³, and the specific gravity of the acid compared to water is 1.8.

Step-by-step explanation:

To find the density of the sulfuric acid we can use the formula density = mass/volume. Since the mass of the sulfuric acid is 18g and the volume is 10 mL, the density of sulfuric acid can be calculated as:

Density of sulfuric acid = mass/volume = 18g/10mL = 1.8 g/mL.

Since 1 mL is equivalent to 1 cm³, the density can also be expressed as 1.8 g/cm³. Now, let's calculate the specific gravity of sulfuric acid, which is the ratio of the density of sulfuric acid to the density of water (1.0 g/mL at room temperature). This can be calculated as:

Specific gravity of sulfuric acid = Density of sulfuric acid / Density of water = 1.8 g/mL / 1.0 g/mL = 1.8.

Therefore, the correct answer would be a) 1.8 g/cm³; 1.8.
