First, in British spelling, you do not use a period after Mrs, but in American spelling, you do: Mrs. This is pronounced Misses, and is a title that shows a woman is married. (It should be noted that although it is very commonly used, not everyone likes this word: some second-wave feminists prefer Ms., since they believe women should not be differentiated by whether they are married or not; there is only one title for men, married or single-- Mr.; but there are two for women, Miss or Mrs., implying that a woman's status in society changes depending on whether she has a husband). That said, you use Mrs. as you would use any title: Mrs. Smith invited her neighbors to her home. Mrs. Jones is studying French.
