Which of the following numbers have just three significant figures? Check all that apply. Choose one or more:

O A. 6.02 x 1023
OB. 6.452
O C. 3.43
O D. 7.02
O E. 12.77
O F. 302

A. 6.02 x 1023

C. 3.43

D. 7.02

F. 302

Explanation:

A. 6.02 consists of three significant figures. 1023 consists of four. When multiplying two values, the answer's significant figures match the multiplicand with lower significant figures (in this case, 6.02).

C. 3.43 consists of three significant figures.

D. 7.02 also consists of three significant figures.

F. 302 is three significant figures as well. If this number was 300 instead, then it would only be one significant figure.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
