80g of dry cleaning fluid has a volume of 50cm³. What is a mass of 1 litre of fluid?

Thanks again! ^_^

1 cubic metre = 1 000 000 cubic cm

1 litre = 0.001 cubic metres

Therefore 1 litre = 0.001 * 1 000 000 = 1000 cubic cm

Now 50 cubic cm of fluid is 80g therefore

20 * 50 = 1000 cubic cm of fluid is 20 * 80 = 1600 g = 1.6 kg

If you remember that a cm³ = mL it is more simple.

80g/50ml(1000ml) = 1600g

I like to remember that a liter is a cube with all sides 10 cm.
And also 1 ml is a tiny cube with all sides 1 cm.
So a liter is 10 times 10 times 10 ml, where ml means milliliters or cc's
And so 1000 ml are in a liter.  Makes sense since milli means 1/1000.

50 cc = 80 grams
1 liter of the fluid = 1,000 cc of the fluid = 20 x 50 cc of the fluid  = 20 x 80 grams = 1,600 grams or 1.6 kilograms
