Darya [45]

Answer:

0.382g

Explanation:

Step 1: Write the reduction half-reaction

Al³⁺(aq) + 3 e⁻ ⇒ Al(s)

Step 2: Calculate the mass of Al produced when a current of 100. A passes through the cell for 41.0 s

We will use the following relationships.

  • 1 A = 1 C/s
  • 1 mole of electrons has a charge of 96486 C (Faraday's constant)
  • 1 mole of Al is produced when 3 moles of electrons pass through the cell.
  • The molar mass of Al is 26.98 g/mol.

The mass of Al produced is:

41.0s \times \frac{100C}{s} \times \frac{1mole^{-} }{96486C} \times \frac{1molAl}{3mole^{-} } \times \frac{26.98gAl}{1molAl} = 0.382gAl

An I.V. infusion order is received for Lidocaine 2 g in 250 ml of 0.9% NaCl to be infused at 3 mg/min. What will the flow rate b
Tamiku [17]

Answer:

The flow rate would be 22.5ml/hr

Explanation:

Volumetric flow rate = Mass flow rate ÷ density

Mass flow rate = 3mg/min = 3mg/min × 60min/1hr = 180mg/hr

Density = mass/volume = 2g/250ml = 0.008g/ml = 0.008g/ml × 1000mg/1g = 8mg/ml

Volumetric flow rate = 180mg/hr ÷ 8mg/ml = 22.5ml/hr

Weight of one mole of carbon = 12.01 g Weight of one mole of oxygen = 16.00 g The molecular weight (gram formula weight) for CO
murzikaleks [220]

Answer:

28.01g

Explanation:

Given the weight of one mole of Cabon as 12.01g and that of oxygen as 16.00g.

The molecular weight of a compound can be gotten by adding the molar weights of the elements that constitutes the compound .

The molecular weight of the compound CO is therefore

equal to the sum of the weight of both elements.

That’s = 12.01g + 16.00g

= 28.01g

Therefore, the molecular weight of CO is 28.01g
