Calculate the volume?

Question

In ml. for each of the following solds:

1. 1kg of Iron (d=7.87g/cm3)

2. 1kg of titanium (d=1.715g/cm3)

Answer 1

These are the conversion factor you'll need,
1 cm^3 = 1 mL
1 kg = 1000 g
since your densities are given in terms of cubic centimeters and grams while you are looking for answers in mL.

Density = mass / volume

1)
7.87 g/mL = 1000 h / v
v = 7.87 g/mL * 1000 g
v = 7870 mL

2)
1.715 g/mL = 1000 g / v
v = 1.715 g/mL * 1000 g
v = 1715 mL

Answer 2

Use in both cases
mass = density x volume

#1) 1000 g = 7.87g/cm3 x V, so V = 127 cm3

#2) the same way.

Answer 3

I think this could be written as 1kg/x=7.87g/1cm^3, and if you cross-multiply it, you get two equal values. For example:
If a/b=c/d, then ad=bc, if of course the numerators are of the same measurements, and the same of the denominators.
so (1000*1)/7.87 would give you your answer, if i'm right, which means the answer is about 127 cubic centimeters
then, using the same equation, 1kg/x=1.715g/1cm^3, and (1000*1)/1.715 would be your answer, which is about 583 cubic cm.

Answer 4

1. 1000 gm /7.87 gm /cm3 = 127.06 cm3

ml have same volume as cm3 so you are done

how about you do the number 2

absolutely no pun intended

Answer 5

Iron: 1000 / 7.87 = 127.064803 cm3
Titanium: 1000 / 1.715 = 583.090379 cm3

Answer 6

42

Answer 7

d= m/v

7.87 g/cm3 /1.1

v (x) 7.87 g/cm3 = 1.1

and I think I got lost after this point

Answer 8

v=m/d;
iron: v=1000g/7.87g/cm3=127.06 cm3;
titanium: v=1000g/1.715g/cm3=583.09 cm3;

Answer 9

1-7870
2-1715

Answer 10

easy its 5 billion cubic miles......I am freakin awsome
