Answer:
1. Density of metal object = <em><u>11000 kg / m3</u></em>.
2. Could the object be gold = <em><u>No,because the density of gold is 19300 kg / m3</u></em>.
Answer:
Factor 1 is a human induced factor and Factor 2 may be influenced by both nature and human factors.
Explanation:
Humans build the buildings, and for example a meteorite can cause different atmospheric changes

At the constant temperatures the lighter the gas molecules, the faster the average velocity of the gas molecules.
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
