an empty glass tube weights 37.3 g. when filled to the rim with water is weighs 54.1g. what is the volume of the glass tube?

54.1 g = mass H2O + mass tube

37.3 g = mass tube
------
16.8 g = mass H2O
volume = mass/density
And I assume the tube is such that the meniscus can be considered as flat.

Thanks....I did that one right.

To find the volume of the glass tube, you need to calculate the difference in weight when it is filled with water and when it is empty.

The weight difference is equal to the weight of the water that fills the tube.

Weight of the empty glass tube = 37.3 g
Weight of the glass tube filled with water = 54.1 g

Weight difference = 54.1 g - 37.3 g = 16.8 g

Since 1 mL of water weighs approximately 1 g, the weight difference can be considered as the volume of the water in milliliters (mL).

Therefore, the volume of the glass tube is 16.8 mL.
