The owner of a mint-condition classic car wrote a letter to his trusted car mechanic offering to sell him the car for $45,000, if he bought it before April 15. The mechanic researched the current market value of the car online and discovered that comparable vehicles were being sold for $48,000. On April 1, he was just leaving his home to drive to the car owner’s house to give him a check for $45,000 when he received a text from the owner stating that he had changed his mind and the car was no longer for sale. The mechanic drove to the owner’s house anyway, where the car was parked out front with a “for sale” sign in its window. The mechanic knocked on the owner’s door and, when he answered, tendered the $45,000 certified check and demanded the car. The owner refused. a. Is there a contract?

b. Was it breached?

x = 2.2*10^23 molecules of H2O

Explanation:

H = 1g

O = 16g

H2O = 1g*2 + 16g

H2O = 18g = 1 mol of H2O

18 g___1 mol of H2O

6.38g__ x = 0.354 mol of H2O

1 mol6.22*10^23 molecules

0.354 mol__x = 2.2*10^23 molecules of H2O
