Determine the final mass
First we need to determine the total mass after the sample mass is added to an additional sample;
Next, divide the total mass by 3
The final mass is calculated as follows;
<em>Hence, the final mass is 17.560943085g</em>
Answer: It can be further reduced or diluted
Explanation:
Solvent is a solution and breaks the material down so the more you add the more it dissolves
Answer:
H- hydrogen
Explanation: Hydrogen is in the first group meaning that it only has 1 valence electron and 1 energy level
Mass=density·volume. The density is 2.70g/mL and the volume is 353mL. So you would multiply 2.70g/mL by 353mL which will give you 953.1g. Hope that helps :)
Answer:
4.46 °C
Explanation:
Step 1: Given and required data
- Energy absorbed (Q): 4430 J
- Specific heat of water (c): 4.186 J/g.°C
Step 2: Calculate the temperature change
We will use the following expression.
Q = c × m × ΔT
ΔT = Q / c × m
ΔT = 4430 J / (4.186 J/g.°C) × 237 g
ΔT = 4.46 °C
The temperature change is 4.46 °C.
