Hi there! Thank you for the opportunity to help you with your question!

Volume percent is given by: weight of solute (in g)/volume of solution (in mL).

Since Volume percent is 0.89%, we have:

0.89% = 2.3g / volume.

This tells us volume =2.3/(0.0089) = 260mL

Please let me know if you need any clarification. Always glad to help!
