Is a mosque whose carpets are perfumed with musk that has alcohol added to it considered impure, and is prayer in it invalid?

Fragrances containing alcohol are impure, and prayer performed with them is invalid. If one prays on a mat with such fragrances, either out of ignorance or forgetfulness, their prayer is valid. However, if one prays while knowing about the impurity, their prayer is invalid. The sisters who perfume the mosque's prayer mats with these fragrances must be advised to stop.
