Please help, thanks in advance!
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.
