The molarity of a salt solution made by dissolving 250.0 grams of NaCl in 775 mL of solution is <u>5.52 M</u> .
<u>Explanation:</u>
The molarity of a solution tells one how many moles of <u>solute</u> one can get <em>per liter</em> of solution.One should remember to must convert this volume to liters by using the conversion factor:
1 L = 10³ml
Sodium chloride (NaCl) has a molar mass of 58.44 g per mol , which means that the sample will contain:
This means that the molarity of the solution will be:
Explanation:
One positive impact of the mining is that the sale of the Bauxite will increase their economic power by bringing in foreign exchange into their economy. This will improve services such as healthcare and infrastructure.
A negative impact is the destruction of the nature preserve and disturbing the ecosystem could lead to a devastating loss in biodiversity. A decrease in biodiversity will increase crop pests and diseases that destroy standing crops, and an increase in the prevalence of diseases in the community.
<span>Calculating average atomic mass is exactly like calculating a weighted average. Perform the following calculation:
(mass1)(percentage1) + (mass2)(percentage2) = average atomic mass
(35.0)(0.75) + (37.0)(0.25) = average atomic mass
Make sure your percentages are in decimal form for this calculation.
One of the other answers given is correct, though the explanation is lacking a bit. Two of the answers can be eliminated immediately: 35.0 amu and 37.0 amu cannot be the average. If the mixture of isotopes was 50% and 50%, then 36.0 amu would be correct; however, the mixture is 75/25. This leaves only one possible answer choice.</span>
Answer:
An aldehyde is a carbonyl group with a carbonyl carbon bonded to hydrogen and can be oxidized to a ketone while a ketone is a carbonyl group with a carbonyl carbon only bonded to oxygen atom and cannot be oxidized
Some of oxidizing agents are potassium dichromates, bradys reagent....
Would that be the river mouth?
