What is the range for the following set of measurements?
7.1 g, 9.8 g, 2.3 g, 8.5 g, 7.4 g, 5.7 g

a. 0.0 g to 10.0 g
b. 2.3 g to 9.8 g
c. 0.1 g
d. 7.1 g to 5.7 g

the way that the mass of carbon can be conserved through cellular respiration is through a process/law called the law of conservation of mass which even tho it undergoes a process, mass is not be destroyed or changed

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
