Question

A baker needs exactly 2,500 chocolate chips to make cookies for the week. Each chocolate chip weighs 4.8 x 10^-4 kg. What is the total mass, in kilograms, of the chocolate chips?

A) 0.012 kg
B) 1.2 kg
C) 12 kg
D) 120 kg

Answer 1

To calculate the total mass of 2,500 chocolate chips each weighing 4.8 x 10^-4 kg, you multiply the mass per chip by the number of chips, resulting in a total mass of 1.2 kg.

Step-by-step explanation:

The student has asked about the total mass of 2,500 chocolate chips where each chocolate chip weighs 4.8 x 10^-4 kg. To find the total mass, you need to multiply the mass of one chocolate chip by the total number of chocolate chips:

Total mass = Mass of one chocolate chip × Number of chocolate chips

Total mass = (4.8 x 10^-4 kg) × 2,500

Total mass = 1.2 kg

So the total mass, in kilograms, of the chocolate chips is 1.2 kg, which corresponds to option B).
