Around each $C$ and $O$ there are $4$ electron pairs, and non-bonding. To a first approximation specifies tetrahedral geometries about $C$ and $O$, and indeed there are.

The $/_H-C-H$ and $/_H-C-O$ bonds have a bond angle of approx. $109.5^@$. The $H-O-C$ bond angle tends to be compressed slightly due to the oxygen lone pairs which are stereochemically active, so maybe the $H-O-C$ bond angle $=$ approx. $104-5^@$. Capisce?

How do you convert 11.0 g $CH_3OH$ to 0.490 M?

And thus $"Moles of methanol"/"Volume of solution"$ $=$ $0.490*mol*L^-1$ $"Methanol"$ has a formula mass of $32.04*g*mol^-1$. And thus $((11.0*g)/(32.04*g*mol^-1))/"Volume of solution"=0.490*mol*L^-1$. Upon rearrangement, $"Volume of solution"=((11.0*g)/(32.04*g*mol^-1))/(0.490*mol*L^-1)$, which is under $1*L$....

How would you calculate the density of methanol ($CH_3OH$)?

And of course, $rho,"density"$ $=$ $"Mass"/"Volume"$. For methanol at $298K$, $rho=0.792*g*cm^-3$. Methanol is immiscible with petroleum ether, $rho=0.653*g*cm^-3$. Would methanol float or sink on/in pet. ether?

Why is $CH_3OH$ miscible in water whereas $CH_3(CH_2)_6OH$ is not?

The longer the alkyl chain, the less soluble in water is the alcohol. Methanol and ethanol are infinitely miscible in water; propanol and butanol have limited solubility. Of course, if...

If you used 30.6 g of methanol $CH_3OH$ to start a fire, how many molecules did you use?

this is the Avogadro's number.It is the number of particles found in one mole of a substance. It is the number of atoms in exactly 12 grams of carbon-12.

The fuel methanol ($CH_3OH$) is made by the reaction of carbon monoxide and hydrogen. What is the balanced chemical equation? How many grams of hydrogen are needed to produce 45.0 grams of methanol?

The balanced equation is: $2H_2+CO to CH_3OH$. One C, one O and 4 H on each side. The molar mass of methanol is $12+4+16=32$ $gmol^-1$ Number of moles: $n=m/M=45/32=1.41$ $mol$...

How many grams of $ CH_3OH$ can be made from 23.12 g of $CO$ and 8.323 of $H_2$?

$CO + 2H_2 rarr CH_3OH$ And (ii) equivalent quantities of carbon monoxide and dihydrogen. $"Moles of carbon monoxide"$ $=$ $(23.12*g)/(28.01*g*mol^-1)=0.825*mol$. $"Moles of dihydrogen"$ $=$ $(8.323*g)/(2.016*g*mol^-1)=2.016*mol$. Clearly, the dihydrogen is in...

What is the mole fraction of methanol in a solution that contains 6.0 mol of methanol and 3.0 mol of water? The formula for methanol is $CH_3OH$.

$chi_"MeOH"$ $=$ $"Moles of MeOH"/"Moles of methanol + moles of water"$ $(6.0*mol)/((6.0+3.0)*mol)=2/3$ as required............. What is the $"mole fraction of water?"$
