Answer:

4 tabletes/dose

Explanation:

mass person = (90 Lb)×(Kg/2.20462 Lb) = 40.823 Kg body

amount of medicine = 50 mg/Kg body.day

frecuency = 2 dose/day

⇒ amount of medicine/day =  (50 mg/kg body.day)×(40.823 Kg body) = 2041.168 mg/day

⇒ mg medicine/dose = (20141.168 mg/day)×(day/ 2 dose) = 1020.584 mg medicine/dose

∴ mg medicine/tablet = 250 mg medicine/tablet

⇒ # tabletes/dose = (1020.584 mg medicine/dose)×(tablet/250 mg medicine) = 4.082 tabletes/dose

⇒ # tabletes/dose ≅ 4 tabletes/dose

How many valence electrons are there in Se atom?
Lena [83]

Answer:

4 valence electrons

Despite the fact that the word silicon has a ubiquitous affiliation with all things electronic, Si itself is not a good electrical conductor. It has 4 valence electrons, meaning that filling its outer shell it can form a very strong lattice with 4 neighboring Si atoms-with no un-bonded electrons remaining

Maria is baking cookies. She mixes water, flour, sugar, baking powder, butter and chocolate chips and then measures the mass of
Mrrafil [7]

Answer:

The law of conservation of mass was obeyed since some of the mass evaporated while the cookies were baking.

Explanation:

Maria mixes water, flour, sugar, baking powder, butter and chocolate chips and then measures the mass of her ingredients.

Initial mass of ingredients = 1053 g

Final mass = 845 g

All these information are not of any great help.

Law of conservation of mass states that:

For any system closed to all transfers of matter and energy, the mass of the system can not change with respect to time, as system's mass cannot change, any mass can neither be added nor be removed.

In this process of baking, considering the cookies as our system, they never formed a closed system. Hence were free for evaporation.

During the process of baking, water from dough must have evaporated and mass must have reduced.

Hence, the law of conservation of mass was not obeyed.
