The morality, molality, and mole fraction of NaOH is mathematically given as

  1. morality= 4 ppm
  2. molality=0.7936m
  3. x1 = 0.152

What are the morality, molality, and mole fraction of NaOH?

Question Parameters:

A solution was made by dissolving 800. 0 g of NaOH in 25,200 g of water.

Generally, the equation for the Molality   is mathematically given as

molality = (mass / molar mass) x (1/ weight of solvent kg)

Therefore

M= (800 /40) x (1 /25.2)

M=0.7936m

Therefore

m= 10 x 18 / 1000

m= 0.18

Hence

x1 = 0.18 - 0.18 x1

1.18 x1 = 0.18

x1 = 0.152

Where the mole fraction is x1 = 0.152 The mass is

m= (800 / 800 + 2000) x 1000

m= 28.57 %

Hence the morality

molality = mg /L

molality= 8000 x 10^-3 / 2 L

morality= 4 ppm

In conclusion, the morality, molality, and mole fraction of NaOH are given respectively as

morality= 4 ppm

molality=0.7936m

x1 = 0.152

Suppose the tax rate on the first​ $10,000 of income is 0​ percent; 10 percent on the next​ $20,000; 20 percent on the next​ $20
dsp73

Answer:

option (A) $32,000 for A and $7500 for B

Explanation:

Given:

Tax rate as:

on the first​ $10,000 of income = 0%

10% on the next​ $20,000

20% on the next​ $20,000

30% on the next​ $20,000

40% on income over​ $70,000

Income of family A = $120,000

Thus,

For A

Up to $10,000 ; tax = 0

Tax amount from $10,000 to $30,000 at 10 % tax rate

= 10% × $20,000

= $2,000

From $30,000 to $50,000 at 20 % tax rate

= $20,000 × 20%

= $4,000

From $50,000 to $70,000 at 30 % tax rate

= $20,000 × 30%

= $6,000

Tax amount above $70,000 to $120,000 at 40 % tax rate

= (120,000 - $70,000) × 40%

= $50,000 × 40%

= $20,000

Therefore,

Total tax bill for family A

= $2,000 + $4,000 + $6,000 + $20,000

= $32,000

Similarly,

For family B

Income of family B = $55,000

Thus,

Up to $10,000 = $0

From $10,000 to $30,000 at 10 % tax rate

= $20,000 × 10%

= $2,000

From $30,000 to $50,000 at 20 % tax rate

= $20,000 × 20%

= $4,000

Tax amount from $50,000 to $70,000 at 30 % tax rate

= ($55,000 - $50,000) × 30%

= $5,000 × 30%

= $1,500

Therefore,

Total tax bill for family B = $2,000 + $4,000 + $1,500 = $7,500

Hence,

The correct answer is option (A) $32,000 for A and $7500 for B

Recommend financial reporting and auditing-related reforms that would likely be effective in preventing or detecting frauds simi
abruzzese [7]

Answer:

The answer is stated below:

Explanation:

If the SEC and the AICPA, worked altogether in order to share the information, they might have detected the fraud prior. The case states that the Madoff Securities does not required to submit the peer review program to AICPA as Friehling, had recorded that he did not perform or conduct any audits.

Recommendation

1. The policy execution for the exchange of the information among the two firms would be useful to detect the fraud.

2. The PCAOB should spend more resources an attending the hotline of whistle blowing through executing the policies which need certain complaints to be addressed effectively.

3. The firms or company should have done more in order to verify the financial statements assertions, which surrounds the investments. The PCAOB need to execute the policy that require the companies (such as Madoff Securities) to correctly answer the inquiries of the auditor.
