Calculate the density of themetal in kg/m3.                                                                                                                                                                2. The speed of sound in air at 313 K is about 354.94 m/s. Calculate this speed in miles per hour.3. Caffeine is a substance whose aroma can be detected by the human nose in the smallest amount. Thethreshold limit is 4.3 × 10^-11 grams per liter of air. If the current price of 25 g of caffeine is PhP 18.1,determine the cost (in PhP) to supply enough vanillin so that the aroma could be detected in a largeaircraft hangar with a volume of 3.0 × 10^8 ft^3.
