Question
d.- Determine the density (in g/mL) of a substance that weighs 0.695 Ib and occupies a volume of 3.4 qt. e. found in a room to be 5.7 x 10' mg/cm. How many grams of CO are present in the room if the rooms dimensions measure 3.5 m x 3.0 m x 3.2 m? A cylindrical piece of metal is 2.03 inches high, has a diameter of 17.0 mm wide, and weighs 31.599 g. Determine its density: Will this object sink or float in water? Volume (cylinder) = rh g- Zinc sulfide is treated with sulfuric acid, resulting in a solution with some undissolved bits of zinc sulfide and releasing hydrogen sulfide gas. If 10.85 g of zinc sulfide is treated with 50.00 mL of sulfuric acid (density- 1.153 g/mL), 65.15 g of solution plus undissolved solid remain. What is the volume (in L) of hydrogen sulfide gas evolved from this reaction? The density of hydrogen sulfide gas is 1.393 g/L.Explanation / Answer
Density= Mass/Volume
Mass= 315.2467 ml
Volume=3217.6 ml
So putting it in formula
=315.2467/3217.6
= 0.0979 g/ml
