1.	How many years would it take to spend Avogadro Number of rupees at the rate of 10 lakh rupees per second ?
Answer» Solution :Avogadro.s Number = `6.022 XX 10^23` If 10 lakh (`10^6`) rupees are spent every second, the number of SECONDS taken in spending `6.022 xx 10^(23)` rupees `=(6.022 xx 10^(23))/10^(6) = 6.022 xx 10^(17)` `therefore` 1 second = `3.169 xx 10^(-8) xx 6.022 xx 10^(17)` `=1.908 xx 10^(10)` YEARS Hence, it will take `1.908 xx 10^10` years to spend Avogadro number of rupees at the rate of 10 lakh rupees PER second.
