Question

1.18)______is how much matter fits into a certain space.
a. mass
b. density
c. volume
1.19)______a brick has a mass of 100 g and a volume of 50 cm³. w
a. 200 g/cm³
b. 2 g/cm³
c. 150 g/cm³

Explanation:

1.18) Density is defined as mass per unit volume, which means it shows how much matter (mass) fits into a certain space (volume). Mass is just the amount of matter. Volume is the amount of space an object occupies.
1.19) Using the density formula \(
ho=\frac{m}{V} \), where \( m = 100\ g \) and \( V=50\ cm^{3} \). Substitute the values: \(
ho=\frac{100\ g}{50\ cm^{3}} = 2\ g/cm^{3} \).

Answer:

1.18) B. Density
1.19) B. \( 2\ g/cm^{3} \)
