What is the molarity of a 0.40 L Solution with 6.2 g KCl?

Chemistry
1 answer:
Kitty [74]3 years ago
8 0

Answer:

Molarity of KCl = 0.03M

Explanation:

Molarity=\frac{W}{GMW} \times \frac{1000}{V(in\,ml)}

Given

Weight of $KCl$ =6.2g

V=0.40 L=400ml

Gram Molecular weight=74.55g

Therefore Molarity = \frac{6.2}{74.55}\times{1000}{400}\\                                =0.03M

BIOCHEMISTRY HELP! You and a lab partner are performing on several molecular analogs to determine Km. One is a substrate analog,
Alina [70]

Answer:

Michaelis constant is known as km which is the substrate concentration that encourages the compound to work at half maximum velocity represented by Vmax/2. Michaelis constant is inversely related to the substrate and the affinity of the enzyme.  

Induced fit model: The premise of the purported induced fit hypothesis, which expresses that the attachment or association of a substrate or some other atom to an enzyme causes an adjustment to the enzyme in order to fit or restrain its activity.  

In substrate, analog Km or Michaelis constant will be high as the substrate will stay because of analogs inhibit activity.

In the transitional state, analog Km will be in the middle of the substrate and product analogs. Progress state analogs are synthetic mixes with a structure catalyzed reaction that looks like the progressing condition of a substrate atom in a compound enzyme.  

In item simple thus Km is the least.  

0.0013 M = product ananlog,

0.025 M=Transition state, and

0.0045 M = Substrate analog

Pepsi has a density of 1.06 g/mL. It has a mass of 370 g. What is the volume of the can of Pepsi?
Ulleksa [173]

Answer:

<h3>The answer is 320.75 mL</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

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

From the question we have

volume =  \frac{340}{1.06}  \\  = 320.7547169...

We have the final answer as

<h3>320.75 mL</h3>

Hope this helps you

Complete this sentence. If mass remains the same while the volume of a substance ________, the density of the substance will____
Andre45 [30]
<span> If mass remains the same while the volume of a substance increases, the density of the substance will decrease. The increase in the volume is called expansion, while the decrease in the volume is called contraction.
</span><span>The density measures how much matter (mass) there is in a given amount of space (volume).  So, if the mass stays the same and the volume increases then there is the same amount of mass ad before but in bigger volume so the density is decreased. </span>
