Saline solutions (NaCl in water) used to deliver intravenous drugs are 0.89%(w/v). What volume of this solution delivers 2.3 g?
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
I hope you enjoy the answer, and I would really appreciate if you could leave a review! Thank you :)
