A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time.
Explanation:
Given
Mass of NO - 824 g
Molar mass of NO - 30.01g/mol
No of moles of NO = Given mass/Molar mass
No of moles of NO = 824/30.01= 27.45 mole
Hence 27.5 moles of NO are formed!

Answer:
5.44 kg/L
Explanation:
Mass = 13.6 kg
Change in water level as a result of Trevor = Volume of Trevor = 2.50 L
Density = ?
The relationship between the three parameters is given as;
Density = Mass / Volume
Density = 13.6 / 2.5
Density = 5.44 kg/L
