Answer:
V = 1.2 × 10⁻⁶ m³
Explanation:
Volume is equal to length × width × height, since we are given these measurements in the question we can simply plug our numbers into the formula.
V = l × w × h
V = 1.64 x 10⁻² × 1.5 x 10⁻² × 4.8 x 10⁻³
V = 1.2 × 10⁻⁶ m³
Explanation:
As it is known that non-electrolytes do not dissociate. Therefore, molarity of such a solution is equal to the osmolarity of solution.
As, molar mass of ethanol = 46.07 g/mol
Therefore, no. of moles of ethanol will be calculated as follows.
No. of moles = 
=
=
mol
As, molarity is moles of solute in liter of solution. Hence, molarity of ethanol is as follows.
Molarity = 
= 
=
mol/L
Since, for the given solution Molarity = osmolarity
Thus, we can conclude that osmolarity of .00001 grams (0.1 mg%) of ethanol in 1 L is
osmol/L.
Answer:
Evaporation
Explanation:
Water in the ocean, rivers, lakes, etc. is part of the hydrosphere, and when that water evaporates it enters the atmosphere
The moles of silicon is 4.651 moles
<u><em>calculation</em></u>
The moles of silicon is calculated using Avogadro's constant
that is according to Avogadro's law
1 mole = 6.02 x 10^23 atoms
? moles = 2.80 x 10 ^24 atoms of silicon
by cross multiplication
= [ ( 1 mole x 2.80 x 10^24 atoms) / ( 6.02 x 10 ^23 atoms)]
= 4.651 moles
Answer:
Multiply the given mole quantity by the ratio of the moles from the chemical formula (moles of desire / moles of given in the formula) x moles given
Explanation:
