A 250 gram sample of water at the boiling point had 45.0 kj of heat added. how many grams of water were vaporized? heat of vapor
Julli [10]
You have 45 kJ of heat added and for every 40.6 kJ added, one mole is able to be vaporized. Find how many moles you can vaporize.

45 kJ / 40.6 kJ = 1.1 moles

Water is roughly 18 g per mole so 1.1 moles x 18 g per mol = 19.95 grams vaporized

Hope I helped!

An object with a mass of 6.9 g raises the level of water in a graduated cylinder from 25.1 mL to 30.4 mL. What is the density of
Nana76 [90]

Answer:

The answer is

<h2>1.30 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass of object = 6.9 g

volume = final volume of water - initial volume of water

volume = 30.4 - 25.1 = 5.3 mL

It's density is

density =  \frac{6.9}{5.3}  \\  = 1.30188679...

We have the final answer as

<h3>1.30 g/mL</h3>

Hope this helps you
