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.
Therefore, you can get about 25 - 2 oz tasting glasses per magnum bottle of wine or about 8 to 12 full-sized pours (each 4 to 6 oz). If you are hosting a large party or event, one case of wine (12 bottles) generally gives you approximately 70 glasses of wine.
