What is the concentration (M) of CH3OH in a solution prepared by dissolving 11.7 g of CH3OH in sufficient water to give exactly

Andrej [43]

Answer:

$3.65~M$

Explanation:

We have to remember the molarity equation:

$M=\frac{mol}{L}$

So, we have to calculate "mol" and "L". The total volume is 100 mL. So, we can do the conversion:

$100~mL\frac{1~L}{1000~mL}=~0.1~L$

Now we can calculate the moles. For this we have to calculate the molar mass:

O: 16 g/mol

H: 1 g/mol

C: 12 g/mol

$(16*1)+(1*4)+(12*1)=32~g/mol$

With the molar mass value we can calculate the number of moles:

$1.7~g~of~CH_3OH\frac{1~mol~CH_3OH}{32~g~of~CH_3OH}=0.365~mol~CH_3OH$

Finally, we can calculate the molarity:

$M=\frac{0.365~mol~CH_3OH}{0.1~L}=3.65~M$

I hope it helps!

If 60.0 ml of a 1.5 m hcl solution is put into a flask and diluted with water to make 2.0 l of solution

77julia77 [94]

Answer:

The molarity of the diluted HCl solution: M₂ = 0.045 M

Explanation:

To find- the molarity of the diluted HCl solution (M₂)

Given- For original HCl solution-

Molarity: M₁ = 1.5 M, Volume: V₁ = 60.0 ml = 0.06 L (∵ 1L = 1000 mL)

Then this original solution is diluted to a volume of 2 L

Thus for the diluted HCl solution-

The Volume of the diluted HCl solution: V₂ = 2 L

So the Molarity of the diluted HCl solution (M₂) can be calculated by the dilution equation:

$M_{1}\times V_{1} = M_{2}\times V_{2}$

$\Rightarrow M_{2} = \frac{M_{1}\times V_{1}}{V_{2}}$

$\Rightarrow M_{2} = \frac{1.5 M\times 0.06 L}{2 L} = 0.045 M$

Therefore, the molarity of the diluted HCl solution: M₂ = 0.045 M

93.0 mL of O2 gas is collected over water at 0.930 atm and 10.0 C.what would be the volume of this dry gas at STP

ExtremeBDS [4]

Let us assume that the oxygen behaves as an ideal gas such that we can use the ideal gas equation to solve for the number of moles of O2.
PV = nRT ; n = PV/RT
Substituting the known values,
n = (0.930 atm)(93/1000 L) / (0.0821 L.atm/mol.K)(10 + 273.15K)
n = 3.72 x 10^-3 mols
At STP, the volume of each mol of gas is equal to 22.4 L.
volume = (3.73 x 10^-3 mols) x (22.4 L/1 mol)
volume = 0.0833 L or 83.34 mL
