Answer:

The solubility of the salt is

46.75g salt/100g of H2O

Explanation:

If 7.70g of water can dissolve 3.60g at 21°C

That is 1.0g of water can dissolve (3.6÷7.7) grams of salt, that is 0.4675_g of salt at 21°C or 100 grams of water can dissolve 100×0.4675 = 46.75g

The solubility of the salt is

46.75g salt/100g of H2O

I need to make up an experiment !! Please help

Question: Baking a Cake Without Flour.

Hypothesis: I think that when I remove the flour from the standard cake recipe, I'll end up with a flat but tasty cake.

Procedure: I baked two cakes during my experiment. For my control, I baked a cake following a normal recipe. I used the Double Fudge Cake recipe on page 292 of the Betty Crocker Cookbook. For my experimental cake, I followed the same recipe but left out the flour. I first obtained a 2-quart mixing bowl.  

Results: My control cake, which I cooked for 25 minutes, measured 4 cm high.  Eight out of ten tasters that I picked at random from the class found it to be an acceptable dessert. After 25 minutes of baking, my experimental cake was 1.5 cm high and all ten tasters refused to eat it because it was burnt to a crisp.

What did I learn?/Conclusion: Since the experimental cake burned, my results did not support my hypothesis.  I think that the cake burned because it had less mass, but cooked for the same amount of time.  I propose that the baking time be shortened in subsequent trials.

<h3>What is Manometer ?</h3>

Manometer is a U shaped instrument which is used to measure the pressure acting on a column of fluid , a difference in the pressure  in the two arms of the manometer causes the liquid to reach different heights.

The difference  in the heights of the Hg columns in Diagram B is17 mm-Hg.

the atmospheric pressure is 769 mm-Hg,

the pressure of the confined gas in mm-Hg = ?

The pressure of the confined gas will be 769-17 = 752 mmHg
