8 concrete blocks were tested in a lab to determine the crushing strength of concrete. The crushing strength of block E was missing from the final records. But the mean crushing strength was recorded as 4.45 tonnes/cm 2 . What was the measured crushing strength of block E ? Block Crushing..

Equal amount of dextro and laevo varieties are got when an optically active compound is synthesized in the lab. The result is a racemic mixture. The two forms called enantiomorphs can be separated from the racemic mixture. This process is called resoluti..
