The enzyme urease enhaces the rate of urea hydrolysis at pH8.0 and 20 degree of centigrade by a factor of 1014. If a given quantity of urea in 5 min at pH 8.0 and 20 degree of centigrade, how long would it take for this amount of urea to be hydrolyzed under the same conditions in the absence of urease

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
