The verb of motion which is appropriate for "to go" is often omitted in Russian when it's obvious or implied. This happens because the grammatical case of the noun/location can already indicate motion towards itself. Since English doesn't have cases for this purpose, we have to make up for it by using a motion verb such as "to go", usually with the preposition "to" following it. For example:
Я домой. - I'm going home. Мы в театр. - We're going to the theater. Вы в кино? - Are you going to the movies? Девочка на почту. - The girl is going to the post office. Мама на работу. - Mom is going to work. Бабушка к нам. - Grandma is coming over (literally "to us").
Hope that helps!
First of all, don't check pronunciation on Google translate. It's trash. Either go to wiktonary or forvo.com.
Secondly, in Russian the O turns into an ah sound when it's not stressed. Молоко (milk) sounds like 'mah lah ko' because the last syllable is accented.
There's only one stressed syllable in Russian words. There's not an easy rule to know where the stress goes, but eventually you'll be able to know. For now, just memorize.
