Answer:
c or d I think but I'm not completely shure
First let us compute for the number of moles of butane
(molar mass = 58.12 g/mol)
number of moles = 145 g / (58.12 g/mol) = 2.49 mol
<span>We use the ideal
gas equation to calculate the volume:</span>
<span> V = n R T / P</span>
V = 2.49 mol * 62.36367 L torr / mol K * 308.15 K / 745
torr
<span>V = 64.35 L</span>
Answer:
6.85 g
Explanation:
Step 1: Given data
- Molar concentration of the solution: 0.200 M (0.200 mol/L)
- Volume of the solution: 100.00 mL (0.10000 L)
Step 2: Calculate the moles of sucrose (solute) required
Molarity is equal to the moles of solute divided by the liters of solution.
M = moles of solute / liters of solution
moles of solute = M × liters of solution
moles of solute = 0.200 mol/L × 0.10000 L = 0.0200 mol
Step 3: Calculate the mass corresponding to 0.0200 moles of sucrose
The molar mass of sucrose is 342.3 g/mol.
0.0200 mol × 342.3 g/mol = 6.85 g
The number that represents the gas phase is V.
The graph shown is the heating curve of a substance X.
The substance is heated from the solid phase (I) until it undergoes fusion (II).
III represents the liquid state of substance X while IV represents the vapourization process of X.
At point V substance X has been converted to the gas phase.
