How do you know if its masculinf or feminin

The easiest way to determine masculine and feminine nouns is to look at the pronoun before it. If the noun is masculine, there will be a "le" or "un" and if it's feminine there will be a "la" or "une", but if it's plural, there will be a "les" or "des", or of it starts with a vowel, there could be a "l' ".

When the noun is plural or starts with a vowel, it is a lot harder to tell, so you have to look at the word. In general (there are always exceptions), if a word ends with -que, -ée, or -elle, it is feminine.

Just a note, there are a lot more masculine words than feminine, so if you really can't figure out which it is, I would defer to the masculine.

Hope this helps :)
