Calculate the volume of CO_(2) obtained at STP when 2.12 g of Na_(2)CO_(3) reacts with excess of dil HCI .
An unbiased coin is tossed. If the result is head, a pair of unbiased dice is rolled and the number obtained by adding the numbers shown on the two faces is noted. If the result is tail, a card from a well shuffled pack of eleven cards numbered 2, 3, 4, ..., 12 is picked and the number on the card is noted. Find the prbability that noted number is either 7 or 8.
