Question

Calculate the density of aluminum if 27.6cm³has a mass of 74.6g

Density:______g/cm³
a)2.70g/cm³
b)2.15g/cm³
c) 2.71g/cm³
d) 2.25g/cm³

Answer 1

The density of aluminum is calculated using the mass-to-volume ratio, and with the given mass of 74.6 grams and a volume of 27.6 cm³, the density is found to be 2.70 g/cm³. The correct option is a.

Step-by-step explanation:

To calculate the density of aluminum, we can use the mass-to-volume ratio. Density is calculated as the mass of object divided by its volume. In this case, we have a mass of 74.6 grams and a volume of 27.6 cm³. The formula to calculate density is:

Density = Mass / Volume

Plugging in the values provided:

Density = 74.6 g / 27.6 cm³

After performing the division, we find that Density = 2.70 g/cm³. Therefore, the correct answer is:

(a) 2.70 g/cm³
