Sedimentary rocks are formed through the deposition and accumulation of sediments, and their subsequent consolidation (diagenesis). Diagenesis is the set of chemical, physical and biological transformations and processes that the sedimentary deposit undergoes upon its deposition, and can lead to the unconsolidated sedimentary deposit in the rock. Litification is the process of becoming rock. The best known lithification processes are compaction, dissolution, cementation, and diagenetic recrystallization.
Explanation: If three potatoes have mass of 667 g that means that each potato weighs 667/3= 222.33 g (approx) so 100 potatoes must be 100*222.33= 22233 g which equals 22.2 kg because 1 g=1000 kg
