As we replace bonding pairs with nonbonding pairs the molecular geometry changes to seesaw (four bonding and one nonbonding), T-shaped (three bonding and two nonbonding) and linear (two bonding and three nonbonding).
There are 12 bottles in a standard case of wine. Each of those bottles normally contains 750 milliliters of wine, giving the case a total of 9 liters. If a case contains anything other than 12 bottles, the wine manufacturer or seller usually notes the change for consumers.
Here are some more fun numbers. One ton of grapes yields approximately 150 gallons of wine. A wine barrel will hold 59 of these gallons of wine which yields 24.6 cases which equates to 295 bottles. For practical purposes, we will round this last number up to 300 bottles of wine per barrel. These numbers are the easy ones because they do not vary.
