How much 3M NaOH (MW=40) can be made from 10.0mL of a 10M solution?

Biology

8 0

Explanation:

The given data is as follows.

              M_{1} = 3 M,           V_{1} = ?

              M_{2} = 10 M,         V_{2} = 10.0 ml

Therefore, calculate the volume of given solution as follows.

              M_{1} \times V_{1} = M_{2} \times V_{2}

Now, putting the given values into the above formula as follows.

            M_{1} \times V_{1} = M_{2} \times V_{2}

            3 M \times V_{1} = 10 M \times 10.0 ml    

                   V_{1} = 33.3 ml

or,                             = 0.033 L        (as 1 ml = 0.001 L)

Since, molarity of NaOH is given as 3 M and its volume is calculated as 33.3 ml.

           Molarity = \frac{\text{mass of solute}}{\text{molar mass of solute}} \times \frac{1}{\text{volume in L}}

               3 M = \frac{mass}{40 g/mol \times 0.033 L}

              mass = 3.96 g

Therefore, we can conclude that mass of NaOH is 3.96 g.

galben [10]
Im not sure how to answer this since there were no choices given but I will answer by telling you what nuclear fusion is...

so basically nuclear fusion is the merging or combining of 2 isotopes, typically isotopes of hydrogen, under conditions of extreme temperature and pressure thus resulting in the release of massive amounts of energy. I think the answer to your question would be new types of electricity because the heat emitted from the reaction could be turned into electricity by using its steam. This is what happens in nuclear reactors

Both Duchenne muscular dystrophy and color blindness are caused by recessive alleles. DMD, unlike color blindness, nearly always
Ronch [10]

Answer: Although both are X-linked recessive conditions, and therefore more likely in males, with the single X-chromosome. The recessive allele in colour blindness occurs at a higher frequency in the population and is a mild condition. Thus colour blindness does occur to a lesser extent in females because it needs the double recessive condition. DMD is a severe, disabling condition with a limited lifespan, and recessive allele frequency much lower, so the double recessive condition in females is very rare.

Explanation: DMD is an X-linked recessive, “nearly always in males” suggest that it also occurs due to a new mutation or some rare condition e.g. double recessive from an affected father and carrier mother, or inactivation of the normal gene in a heterozygote. It is also found that the defective allele is not completely recessive and that female carriers may exhibit mild to moderate effects.

colour blindness is polygenic, although the genes are all X-linked. It is more common in males than females. Females can carry two recessive alleles and so express the phenotype, but this is uncommon because the frequency of the recessive gene is low.

There are similarities in that both are X-linked recessives, therefore commonly expressed in males, who only have one X chromosome. The gene frequency of the colour blindness recessive is much higher than that of DMD, so the double recessive condition, which affects females, is more likely to be seen with colour blindness. In addition, DMD is a severe condition associated with disability and limited lifespan, which reduces the probability of mating between an affected male and carrier female
