How do quartz deposits form?
Quartz is a mineral! 1 litre = 0.87987663 Imperial quarts
Indeed. Quartz is SiO2 and is a very abundant mineral in the Earth's crust. What you want are quarts. And to do that you need a conversion factor. 1L = 1.0567 US quarts i.e. Convert 3.50 L to quarts 3.50 L x (1.0567 qts / 1 L) = 3.69845 qts which is rounded to three significant figures to match the precision of the original quantity, and we get 3.70 qts.
