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!
Answer:
The answer is
<h2>1.30 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

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

We have the final answer as
<h3>1.30 g/mL</h3>
