What mass of Cu(NO₃)₂ (187.6 g/mol)is present in 25.0 g of 1.00 m Cu(NO₃)₂(aq)?

Question

Quizplus · Accepted Answer

The molarity (M) is defined as moles of solute per liter of solution. Given a 1.00 M solution, it means there is 1 mole of Cu(NO3)2 per liter of solution. The mass of Cu(NO3)2 in 25.0 g of this solution cannot be directly calculated without knowing the volume of the solution. However, the question seems to be incorrectly asking about the mass of the solute in a given mass of solution, which is not directly related to molarity. Assuming the intention was to ask about a solution prepared by dissolving 25.0 g of Cu(NO3)2 in enough water to make 1 liter of solution, the mass of Cu(NO3)2 would still be 25.0 g, making all the provided options incorrect under this interpretation. However, without a clear connection between the mass of the solution and its molarity or volume, the question as posed does not provide a direct way to calculate the answer. Therefore, the response is based on an interpretation that might not have been intended, highlighting a need for clarification in the question.
