The amount of pyridoxine (in grams) in a multiple vitamin is normally distributed with mean = 110 grams and standard deviation =

25 grams. What is the probability that a randomly selected vitamin will contain between 82 and 100 grams of pyridoxine?

Answer:

0.21108

Explanation:

Given,

Mean,

\mu = 110\text{ gram}

Standard deviation,

\sigma = 25\text{ gram}

Let X represents the amount of pyridoxine contained by vitamin,

So, the probability of vitamin will contain between 82 and 100 grams of pyridoxine,

= P( 82 ≤ X ≤ 100 )

P(\frac{82-\mu}{\sigma}\leq \frac{X-\mu}{\sigma}\leq \frac{100-\mu}{\sigma})

P(\frac{82 - 110}{25}\leq z \leq \frac{100-110}{25})

P(-1.12\leq z\leq -0.4)

P(z\leq -0.4)-P(z\leq -1.12)

=0.34458-0.13350

= 0.21108

How many ml of a 0.50m solution of hno3 solution are needed to make 500 ml of 0.15m hno3
Anna71 [15]

Answer:

150.0 mL.

Explanation:

  • It is known that the no. of millimoles of HNO₃ before dilution = the no. of millimoles of HNO₃ after dilution.

∵ (MV) before dilution = (MV) after dilution.

<em>∴ V before dilution = (MV) after dilution / M before dilution</em> = (0.15 M)(500.0 mL)/(0.50 M) = <em>150.0 mL.</em>

A solution at 25 degrees Celsius is 1.0 × 10–5 M H3O+. What is the concentration of OH– in this solution? 1.0 × 10–5 M OH– 1.0 ×
Triss [41]

Answer:

1.0 × 10⁻⁹ M.

Explanation:

<em>∵ [H₃O⁺][OH⁻] = 10⁻¹⁴.</em>

[H₃O⁺] = 1.0 x 10⁻⁵ M.

<em>∴ [OH⁻] = 10⁻¹⁴/[H₃O⁺]</em> = 10⁻¹⁴/(1.0 x 10⁻⁵ M) = <em>1.0 × 10⁻⁹ M.</em>

A 12.0% sucrose solution by mass has a density of 1.05 gem, what mass of sucrose is present in a 32.0-mL sample of this solution
natulia [17]

Answer:

Option C. 4.03 g

Explanation:

Firstly we analyse data.

12 % by mass, is a sort of concentration. It indicates that in 100 g of SOLUTION, we have 12 g of SOLUTE.

Density is the data that indicates grams of solution in volume of solution.

We need to determine, the volume of solution for the concentration

Density = mass / volume

1.05 g/mL = 100 g / volume

Volume =  100 g / 1.05 g/mL → 95.24 mL

Therefore our 12 g of solute are contained in 95.24 mL

Let's finish this by a rule of three.

95.24 mL contain 12 g of sucrose

Our sample of 32 mL may contain ( 32 . 12) / 95.24 = 4.03 g
