Copper Ladle
Please help me with my Chem HW?
1) How many milliliters of water will it take to fill a 2 L bottle that already contains 1.87 L of water?
2) A piece of copper wire is 150 cm long. How long is the wire in millimeters? How many 50 mm segments of wire can be cut from the length?
3) The ladle at an iron foundry can hold 8500 kg of molten iron. 646 metric tons of iron are needed to make rails. How many ladlefuls of iron will it take to make 646 metric tons of iron? (1 metric ton _ 1000 kg)
I need to show my work so please explain
thank you
2 - 1.87 =0.13 L = 130 mL
150 cm = 1500 mm
1500/ 50=30
