<u>Answer:</u>

<u>For A:</u> The 0.0132 grams is required per pound of the body weight.

<u>For B:</u> The dost required for 191 lb patient is 5.96 grams.

<u>Explanation:</u>

  • <u>For A:</u>

We are given:

Medication requirement = 5.98 mg/kg

To convert the given amount in grams per pounds, we use the conversion factor:

1 kg = 2.20462 lb

1 g = 1000 mg

Converting the value into grams per pounds, we get:

\Rightarrow (\frac{5.98mg}{kg})\times (\frac{1g}{1000mg})\times (\frac{2.20462lb}{1kg})\\\\\Rightarrow 0.0132g/lb

Hence, the 0.0132 grams is required per pound of the body weight.

  • <u>For B:</u>

To calculate the amount of medication for 191 lb patient, we use unitary method:

For 1 lb body weight, the amount required is 0.0132 grams.

So, for 191 lb body weight, the amount required is \frac{0.0312g}{1lb}\times 191lb=5.96g

Hence, the dost required for 191 lb patient is 5.96 grams.

What is the mass of water necessary to generate 11.2 L of hydrogen gas if calcium metal reacts with water at standard temperatur
12345 [234]

Answer:

The mass of water is 18 g

Explanation:

The reaction of calcium with water can be represented in the equation below:

Ca + 2H₂O --------->Ca(OH)₂ +H₂

1 Mole of gas at STP = 22.4L

From the displacement reaction above, calculate the mass of water that will produce 22.4L of hydrogen gas at STP.

Mass of 2H₂O = 2(2x1 + 16) = 2X18 = 36 g/mol

Using proportional analysis;

36 g of 2H₂O produced 22.4 L of H₂, then

what mass of 2H₂O will produce 11.2L of  H₂ ?

Mathematically,

22.4 L ----------------------------------> 36g

11.2 L -----------------------------------> ?

Cross and multiply, to obtain the expression below

= (11.2 X 36)/22.4

= 18 g

Therefore, the mass of water is 18 g

The specific heat of zinc is 0.39 J/g*°C. How much energy needed to change the temperature of 34g of zinc from 22°C to 57°C. Is
Svetlanka [38]

Answer:

464.1 J absorbed.

Explanation:

Given data:

Specific heat of zinc =  0.39 J/g°C

Mass of zinc = 34 g

Temperature changes = 22°C to 57°C

Energy absorbed or released = ?

Solution:

Formula:

Q = m.c. ΔT

Q = amount of heat absorbed or released

m = mass of given substance

c = specific heat capacity of substance

ΔT = change in temperature

ΔT = 57°C -  22°C

ΔT = 35°C

Q = m.c. ΔT

Q = 34 g. 0.39 J/g°C. 35°C

Q = 464.1 J
