Temp must be Kelvin
38 C = <span> <span> <span> 311.15 </span> </span> </span> K
Volume at STP = 8.50 liters * (273.15 / 311.15) * (725 / 760) =
<span> <span> <span> 7.1182746306 </span> </span> </span> Liters

The formula to use is:

Volume at STP = Present Volume * (273.15 / Present Temp °K) * (Present Pressure (Torr) / 760)

How many grams of sodium chloride are dissolved in 375 ml of a 0.90% saline solution?
liq [111]

Answer:

337.5 g NaCl

Explanation:

.90% saline solution = 90g saline (NaCl)/100mL water (H2O)

1. Use 375 mL to find mass

375 mL × (90 g NaCl/100 mL) = 337.5 g NaCl in 375 mL .9% saline solution

A cube of aluminum (density = 2.70 g/ml) has a mass of 17.2 g. what is the edge length of the cube?
Helen [10]
<span>The formula for mass, which is mass = density x volume, can be rewritten as volume = mass/density. We can deduce the volume of the cube as the mass and density are given: 17.2g/2.7g/ml = 6.37ml. Now that the volume of the cube is known, we can deduce the edge length. Volume = length x width x height, so 6.37 = X^3. We then take the cube root of 6.37 to discover the value of x, which will be the edge length of the cube. The edge length of the cube is 1.85 cm.</span>

Benadryl is used to treat itchy skin in dogs. The recommended dosage is 1 mg per pound. What mass of Benadryl, in milligrams, sh
bulgar [2K]

Answer:

The mass of Benadryl that should be given to the dog is 58.6 mg

Explanation:

First, let´s convert the mass of the dog to pounds:

1 pound = 0.454 kg. Then:

26.6 kg * (1 pound / 0.454 kg) = 58.6 pounds

Since the recommended dosage is 1 mg per pound, the mass of Benadryl that should be given to the dog is  (58.6 pounds * (1 mg / 1 pound)) 58.6 mg.
