Koliko grama ima ovo pakovanje?

Because koliko is the question word asking about quantity: how much / how many.

In this sentence, koliko grama means how many grams. Serbian often puts the question word or question phrase first, just like English does.

So:

• Koliko? = How much? / How many?
• Koliko grama? = How many grams?

After words that ask about quantity, like koliko, Serbian uses a special quantity form of the noun, usually the genitive.

So with gram, you say:

• jedan gram = one gram
• dva grama = two grams
• pet grama = five grams
• koliko grama = how many grams

So grama is the correct form after koliko.

It can mean either, depending on what comes after it.

• Koliko vode? = How much water?
• Koliko knjiga? = How many books?
• Koliko grama? = How many grams?

In this sentence, since grams are being counted as a unit, English uses how many.

Because pakovanje is a neuter noun, and the demonstrative must agree with it.

Serbian this changes by gender:

• ovaj for masculine
• ova for feminine
• ovo for neuter

Since pakovanje is neuter, you say ovo pakovanje = this package / this pack.

A big clue is the ending -nje. Nouns ending in -nje are very often neuter in Serbian.

So:

• pakovanje = neuter
• therefore: ovo pakovanje
• and the verb is singular: ima

You do still need to learn nouns individually, but -nje is a very helpful pattern.

Here pakovanje means something like package, pack, or packaging unit—the item as sold.

For example, it could mean:

• a pack of pasta
• a package of candy
• a container or retail pack of some product

It does not usually mean a mailed parcel in the same everyday sense as English package can. For a parcel, Serbian often uses paket.

So in a shopping/product context, pakovanje is very natural.

Ima is the 3rd person singular present form of imati, meaning to have.

Literally, the Serbian sentence is structured like:

How many grams has this package?

That sounds a bit unusual in natural English, but it is normal in Serbian.

So:

• ovo pakovanje ima 500 grama = this package has 500 grams
• Koliko grama ima ovo pakovanje? = How many grams does this package have?

Because Serbian does not form questions with a helping verb like English do/does in this kind of sentence.

English needs:

• does this package have... ?

Serbian simply uses the main verb directly:

• ima ovo pakovanje...?

So ima already carries the meaning needed for the question. No extra word equivalent to English does is required.

It is in the nominative, because it is the subject of the sentence.

The structure is:

• koliko grama = quantity phrase
• ima = verb
• ovo pakovanje = subject, this package

So ovo pakovanje is nominative singular neuter.

In practical learner terms, it is the form used after quantity expressions like koliko.

More technically, this is the genitive form used with amounts and measurements.

That is why you get:

• koliko grama
• pet grama
• mnogo grama

A good rule to remember is: after words about quantity, Serbian often uses the genitive form.

Serbian word order is more flexible than English, but the most natural neutral question usually puts the question phrase first.

So:

• Koliko grama ima ovo pakovanje? = neutral, natural
• Ovo pakovanje ima koliko grama? = possible, but sounds more marked or surprised
• Koliko grama ovo pakovanje ima? = also possible

Starting with koliko grama makes it immediately clear what information is being asked for.

Yes. It sounds normal, especially in contexts like shopping, cooking, labels, or comparing products.

For example, you might ask it when holding a product in a store and checking its size or weight.

A slightly more formal alternative would be:

• Koliko grama sadrži ovo pakovanje? = How many grams does this package contain?

But ima is very common and natural in everyday speech.

Yes. This sentence pattern is very useful and easy to reuse.

For example:

• Koliko kilograma ima ova kutija? = How many kilograms does this box have?
• Koliko litara ima ova boca? = How many liters does this bottle have?
• Koliko komada ima ovo pakovanje? = How many pieces are in this package?

So the pattern is:

Koliko + unit + ima + thing?

Yes, depending on what you mean.

• ovo pakovanje = this package (near me)
• to pakovanje = that package (near you / already mentioned)
• ono pakovanje = that package over there

So if you are holding the product, ovo pakovanje is the natural choice.
