mg
Explanation:
Total dosage of medicine to be taken in a day
mg
Total weight of one pill 
mg
Number of pills required is equal to total dosage of medicine divided by the weight of one pill.
Hence,
Number of pills
Answer:
In full volume it contain 0.12 moles.
Explanation:
Given data:
Total volume= Vt = 2.9 L
Decreased volume= Vd = 1.2 L
Number of moles of air present in decreased volume= n = 0.049 mol
Number of moles of air in total volume= n = ?
Solution:
Formula:
Vt/ Vd = n (in total volume) /n ( decreased volume)
2.9 L / 1.2 L = X / 0.049 mol
2.42 = X / 0.049 mol
X = 2.42 × 0.049
X = 0.12 mol
To determine the formula units of the given compound, we need to convert from grams to moles first then convert it to formula units by using the Avogadro's number. We do as follows:
23.5 g <span>Sb2S3 ( 1 mol / 339.7 g ) ( 6.022 x 10^23 formula units / mol ) = 4.17x10^22 formula units </span><span>Sb2S3</span>
