Answer:
0.171 M
Explanation:
Step 1: Given data
- Mass of H₃PO₄ (solute): 3.35 g
- Volume of solution (V): 200 mL
Step 2: Calculate the moles of solute
The molar mass of H₃PO₄ is 97.99 g/mol.
3.35 g × 1 mol/97.99 g = 0.0342 mol
Step 3: Convert "V" to liters
We will use the conversion factor 1 L = 1000 mL.
200 mL × 1 L/1000 mL = 0.200 L
Step 4: Calculate the molarity of the solution
We will use the definition of molarity.
M = moles of solute / liters of solution
M = 0.0342 mol/0.200 L = 0.171 M
Water is not alive because it has no living organisms.
Answer:
1. Flower
- contain the sexual organs of the plant
- attract insect for pollination
- produce fruit carries the seed during fertilization.
2. Leaf
- capture sunlight for photosynthesis
- responsible to make food
- evaporate water molecules
- movement of oxygen and carbon dioxide in and out to plant
3. Stem
- transport water and nutrients from root to leaves.
- support leaves and branches
- in some plants are photosynthetic
4. Root
-provide support by anchoring the plant
- absorb water and nutrients for growth
- store sugars and carbohydrates to perform other functions
