Answer:
b. glass and charcoal
Explanation:
Step 1: Given data
- Density of Glass: 2.6 g/mL
- Density of charcoal: 0.57 g/mL
- Density of platinum: 21.4 g/mL
Step 2: Determine which material will float in molten lead
Density is an intrinsic property of matter. Less dense materials float in more dense materials. The materials whose density is lower than that of lead and will therefore float on it are glass and charcoal.
Answer:
1.52 M
Explanation:
Molarity of a solution is calculated as follows:
Molarity = number of moles (n) ÷ volume (V)
Based on the information given in this question,
Volume of soda (V) = 9.13 L
number of moles = 13.83 mol
Molarity = 13.83 ÷ 9.13
Molarity = 1.52 M
Less stable should be the answer.as I think
I hope this helps you
