If the mass of an object stays the same, but its volume increases, the density of the object will 𝗮) decrease.

Density is defined as mass divided by volume. If the mass remains constant while the volume increases, the density will decrease since the denominator (volume) is getting bigger while the numerator (mass) stays the same.

To calculate the density of the sphere, we need to use the formula: density = mass / volume.

The volume of a sphere can be calculated using the formula: volume = (4/3) * π * r³, where r is the radius.

Given:
Mass = 12 g
Radius = 2 cm

First, calculate the volume:
volume = (4/3) * π * (2 cm)³ = (4/3) * 3.14 * 8 cm³ = 33.49 cm³ (approximately)

Now, calculate the density:
density = mass / volume = 12 g / 33.49 cm³ ≈ 0.358 g/cm³

Therefore, the density of the sphere is approximately 0.358 g/cm³.

The closest option to this density is option 𝗮) 0.36 g/cm.

The correct formula to calculate the volume of a ball (or sphere) is:

𝗔) v = (4/3)πr³

where "v" represents volume and "r" represents the radius of the ball.

Hence, the correct option is 𝗔) v = (4/3)πr³.

The measurement of mass per unit volume is called density.

So, the correct answer is option 𝗱) density.

To find the mass, we can use the formula: mass = density * volume.

Given:
Density = 2.5 g/mL
Volume = 20 mL

Calculating the mass:
mass = 2.5 g/mL * 20 mL = 50 g

Therefore, the mass of the substance is 50 g.

Hence, the correct answer is option 𝗱) 50 g.

To find the density of the unknown liquid, we can use the formula: density = mass / volume.

Given:
Mass = 6 g
Volume = 12.0 mL

Calculating the density:
density = 6 g / 12.0 mL = 0.5 g/mL

Therefore, the density of the unknown liquid is 0.5 g/mL.

This value was determined by dividing the mass of the liquid (6 g) by its volume (12.0 mL) using the density formula.
