Hi,

I'm just wondering, if density of water is 1 g / cm3, and you have 5 L, how does that become 5 kg?

I've attached the answer explanation from qVault here. Any help would be appreciated!

Also, I know people say that qVault is slighter harder than the real test, but what about in terms of types of questions? Is it more theoretical and lab-based, like qVault is, or is it more complicated calculations, like on Destroyer?

Thanks!! (I'm taking my exam tomorrow - I guess I should sleep soon!!)

Convert the cm3 into mL (it's the same thing already).

Then you have to convert mL into L, then you multiply by the 5 L. All the units cancel except grams as seen below.

(1 g / mL)*(1000 mL / 1 L)* (5L)
