Answer: Lysosomes
Explanation: The lysosome is an organelle that contains digestive enzymes and acts as the organelle-recycling facility of an animal cell. It breaks down old and unnecessary structures so their molecules can be reused. Lysosomes are part of the endomembrane system, and some vesicles that leave the Golgi are bound for the lysosome.
Answer:
3.011 × 10²³ atoms of Al
Explanation:
Given data:
Number of moles of Al₂(SO₄)₃ = 0.25 mol
Number of atoms of Al = ?
Solution:
In one mole of Al₂(SO₄)₃ there are 2 moles of Al.
In 0.25 mol × 2 = 0.5 mol
1 mole of any substance contain 6.022 × 10²³ atoms.
In 0.5 moles of Al:
1 mole contain 6.022 × 10²³ atoms.
0.5 mol × 6.022 × 10²³ atoms/ 1 mol
3.011 × 10²³ atoms
Based on their percent concentration, the 5% sugar solution contains more water.
<h3>What is the concertation of a solution?</h3>
The concentration of a solution is the amount of solute dissolved or present in a given volume of solution.
Concentration of solutions can be expressed as either:
- molar concentration
- mass concentration
- percentage concentration
The concentration of the sugar solutions are given as percent concentration.
The 5% sugar solution contains 5% sugar and 95% water
The 10% sugar solution contains 10% sugar and 90% water.
Therefore, the 5% sugar solution contains more water.
