The number 250 mg tablets of Metronidazole that are needed to make 150 ml of suspension containing 100 mg/ml
250mg= 150 ml
what about 100 ml = ? Mg
by cross multiplication
150 ml x 250 mg/100 ml = 60 Mg of 250 mg is needed
Answer:
To separate an insoluble solid from a soluble solid: Mixing the mixture with water, filtering out the insoluble solid, and then evaporating the water to isolate the soluble solid.
Explanation:
If you would draw the Lewis structures of these atoms, you would see that A has 2 electron pairs and 2 lone electrons (that can bond). For B you’d see that you only have 1 electron that can form a bond. This means that 1 atom of A (2 lone electrons) can bond with 2 atoms of B. To know the kind of bond you have to know wether or not there will be a ‘donation’ of an electron from one atom to another. This happens when the number of electrons on one atoms is equal to the number of electrons another atom needs to reach the noble gas structure. As you can see, this is not the case here. This means that you get an AB2 structure with covalent character.
The gravitational force acting on an object is its weight.
the answer is C.
