Answer:
(1) 720 seconds (2) 10800 seconds (3) 17 dozens (4) 1.45 x (5) 13.29 moles
Explanation:
(1) 720 seconds
1 minute = 60 seconds
12 minutes = 720 seconds (12 x 60)
(2) 10800 seconds
1 hour = 60 minutes 1 minute = 60 seconds
3 x 60 = 180 minutes in 3 hours
180 x 60 = 10800 seconds in 180 minutes that are in 3 hours
(3) 17 dozens
1 dozen = 12
204 ÷ 12 = 17 dozens
(4) 1.45 x
8.00 moles CO2 x = 24.0 moles atoms
24.0 moles x = 1.45 x
(5) 13.29 moles
sorry but I'm not fully sure if this one is correct
8 x x
= 13.29 moles
