The number of particles : 2.75 x 10²¹
<h3>Further explanation </h3>
A mole is a unit of many particles (atoms, molecules, ions) where 1 mole is the number of particles contained in a substance that is the same amount as many atoms in 12 gr C-12
1 mole = 6.02.10²³ particles
N = number of particles
No = Avogadro number (6.02.10²³)
n = number of moles
While the number of moles can also be obtained by dividing the mass (in grams) with the molar mass of element or molecule
0.75 gram sample of Calcium Nitrate; Ca(NO₃)₂
MW of Ca(NO₃)₂ : 164.09 g/mol
The number of particles
We would all DIE and end up DEAD
Answer:
The correct answer is A: Hypertonic solution
Explanation:
Syrup is a solution with a <u>high concentration of sugar</u>. When you put the fruit in this solution, the syrup concentration is higher than the sugar concentration inside the fruit, this is called an <u>hypertonic solution</u>. Consequently, there is a gradient of concentration between the interior of fruit cells and the exterior. The water will go out from the cells towards the exterior, in favor of the concentration gradient. In this way, you are removing water from inside the fruit (drying).
Hi! Are you looking for molarity?
