Operations with units”: Determine the units of the answers to the following problems. 1) 5280 m x 1 km/ 1000 m
= 5.28__

2)12.5 cm x 10.0 cm = 125__

3) 52.5 kg/ 2.8 kg = 19__

4)

56.5 g -38.2 g
————————————=0.22
8.2 cm x 1.8 cm x 5.6 cm

5) 55.2 g + 26.8 g + 12.3 g
= 94.3__

6)
(20.5 mL) (1.00 g/mL)(12.8°C)
= 262__
