Questions asked by users might not always be phrased in the clearest way.
This appears to be a set of starting materials and their molecular weights, likely for a chemical reaction. However, you haven't specified what you need to calculate. To provide a valid response, please state the specific calculation you require. For example:
What is the stoichiometric ratio of P2NP to hydroxylamine hydrochloride?
What mass of hydroxylamine hydrochloride is needed to react with 5g of P2NP?
What is the theoretical yield of the product?
Providing more context will allow me to assist you with a chemistry-based response.
