0.125 g=(0.125 g)(1000 mg/1g)=125 mg.
Then, we need 125 mg of ampicillin.
5 ml of liquid suspension contains 250 mg of ampicilling , therefore:
5 ml----------------250 mg of ampicilling
x--------------------125 mg of ampicilling
x=(5 ml * 125 mg of ampicilling) / 250 mg of ampicilling=2.5 ml
Answer: we require 2.5 ml
Well i did some research and i found out now im not sure if this is completely true but supposedly tachyons are even faster than the speed of light
Answer: Chloroplasts
Reasoning: I just had my 830th lesson in school about these
Answer:
30.8 grams of nitric acid are produced
Explanation:
Let's state the reaction:
3 NO₂ + H₂O → 2 HNO₃ + NO
If water is the excess reagent, then the limiting is the gas.
We convert the mass to moles:
45 g . 1 mol/ 46 g = 0.978 moles
Ratio is 3:2. 3 moles of gas can produce 2 moles of acid
Then, 0.978 moles may produce (0.978 . 2) /3 = 0.652 moles of acid
This is the 100% yield, but in this case, the percent yield is 75%
0.652 moles . 0.75 = 0.489 moles
Let's convert the moles to mass → 0.489 mol . 63g / 1mol = 30.8 g
