Question

In the lab, a student fills a dry 50 mL graduated cylinder with 15 mL of water. The mass of the water in the graduated cylinder was 15.125 grams at 25°C. What is the true volume of the water measured in the graduated cylinder? The density of water at 25°C is 0.99707 g/mL

Answer 1

`(15.125 g)/(? mL) = (.99707 g)/(mL)`

?=15.044 mL

Answer 2

`V=(m)/(\rho)`

Step-by-step explanation:

Hi, you know for sure that there are 15.125 gr of water in hte cylinder. Also you know that at 25°c the density of water is 0.99707 g/ml

So the true volume is:

`V=(m)/(\rho)`

`V=(15.125 g)/(0.99707g/ml)`

`V=15.169ml`
