Question
Problem PageQuestionA chemist adds 500.0mL of a /0.128gL copper(II) fluoride CuF2 solution to a flask.Calculate the mass in grams of copper(II) fluoride the chemist has added to the flask. Round your answer to 3 significant digits.
Solution
To solve this problem, we need to use the formula for concentration which is mass/volume.
Given:
- Volume (V) = 500.0 mL = 0.5 L (since 1L = 1000mL)
- Concentration (C) = 0.128 g/L
We are asked to find the mass (m).
The formula is rearranged to solve for mass (m):
m = C * V
Substitute the given values into the formula:
m = 0.128 g/L * 0.5 L
m = 0.064 g
So, the chemist has added 0.064 grams of copper(II) fluoride to the flask.
