I believe that the ice cube, being that it still has almost all of its properties, would still have a mass of 25 g after melting
answer 3
Explanation:
when you multiply you round to the lowest number of sig figs
Answer: 1.31 moles sulfur
Explanation:
Okay, so this problem involves using molar mass - something we can get from the periodic table. Sulfur has 32.06 grams per mole, or g/mol as sometimes we write it more simply.
How the problem should be set up is something like this:
42.0 grams sulfur times 1 mole sulfur divided by 32.06 grams sulfur, or
(42.0 g) x (1 mole) / (32.06 g)
This should equal 1.310043668122 moles of sulfur.
Taking significant figures into account, we would round the answer to 1.31 moles of sulfur.
