Answer

Explanation:

Step1: Convert apples to dozens

We know 1 dozen = 12 apples. So, to find the number of dozens in 90 apples, we divide 90 by 12. The number of dozens of apples is $\frac{90}{12}= 7.5$ dozens.

Step2: Find the mass

Since 1 dozen apples has a mass of 2.0 kg, to find the mass of 7.5 dozens of apples, we multiply the number of dozens (7.5) by the mass per dozen (2.0 kg). So, the mass is $7.5\times2.0 = 15$ kg.

Answer:

15 kg
