Answer:
58g
Explanation:
In order to solve this problem, you must take a look at the solubility graph for potassium nitrate.
Now, the solubility graph shows you how much solute can be dissolved per 100g of water in order to make an unsaturated, a saturated, or a supersaturated solution.
You're looking to make a saturated potassium nitrate solution using
50g of water at 60∘C. Your starting point will be to determine how much potassium nitrate can be dissolved in 100g of water at that temperature in order to have a saturated solution.
As you can see, the curve itself represents saturation.
If you draw a vertical line that corresponds to 60∘C and extend it until it intersects the curve, then draw a horizontal line that connects to the vertical axis, you will find that potassium has a solubility of about
115g per 100g of water. Your answer is 58g of potassium nitrate
Your answer is D. Since there is little to no magnetic field to wire, if it is copper which most wires are, there will be no voltage in a wire.
Answer: 0.33M CaBr2
Explanation: Molarity is expressed in moles of solute over liter solution.
M= n solute / L solution
Solution:
First convert mass of CaBr2 to moles using its molar mass
Ca = 40
Br = 80 x 2 answer is 200 g CaBr2.
50.0g CaBr2 x 1 mole CaBr2 / 200 g CaBr2 = 0.25 moles CaBr2
Next convert mL to L
750.0 mL x 1L / 1000mL
= 0.75 L
Substitute the values for M.
M= 0.25 moles CaBr2/ 0.75 L
= 0.33 M CaBr2
