Question

The density of aluminum is 2.7 grams per cm'.

How many grams does 12 cm of aluminum
weigh?

Answer 1

32.4grams

Step-by-step explanation:

Density of a substance can be calculated as follows:

Density = mass ÷ volume

According to this question, the density of aluminum is 2.7g/cm³ while its volume is 12 cm³. The mass of aluminum is therefore,

2.7 = m/12

m = 12 × 2.7

m = 32.4grams.

The mass of aluminum is 32.4grams
