Answer:
The final temperature = 848.7 K or 575.7 °C
Explanation:
Step 1: Data given
Temperature = 25.0 °C = 298 K
Volume = 158 mL = 0.158 L
The volume increases to 450 mL = 0.450 L
The pressure is constant
Step 2: Calculate the final temperature
V1/T1 = V2/T2
⇒with V1 = the initial volume = 0.158 L
⇒with T1 = the initial temperature = 298 K
⇒with V2 = the increased volume = 0.450 L
⇒with T2 = the new temperature = TO BE DETERMINED
0.158 L / 298 K = 0.450 L / T2
T2 = 0.450 L / (0.158L/298K)
T2 = 848.7 T
The final temperature = 848.7 K or 575.7 °C
Answer:
Mass = 2.12 g
Explanation:
Given data:
Volume of KMnO₄ = 255 mL (255/1000 = 0.255 L)
Molarity = 0.0525 M
Mass in gram = ?
Solution:
First of all we will calculate the number of moles.
<em>Molarity = number of moles of solute / volume in litter</em>
0.0525 M = number of moles of solute / 0.255 L
Number of moles of solute = 0.0525 M ×0.255 L
Number of moles of solute = 0.0134 mol
Mass in gram:
<em>Number of moles = mass/ molar mass</em>
Mass = moles × molar mass
Mass = 0.0134 mol × 158.04 g/mol
Mass = 2.12 g
Answer:
one mole of HgO will give one mole of Hg.
Explanation:
Given data:
Moles of HgO = 1 mol
Moles of Hg = ?
Solution:
Chemical equation:
2HgO → 2Hg + O₂
Now we will compare the moles of Hg with HgO from balance chemical equation.
HgO : Hg
2 : 2
1 : 2/2×1 = 1 mol
So, one mole of HgO will give one mole of Hg.
