Allow it to air dry and then brush the baking soda off of the clothing. This step can be repeated until the gasoline is fully removed. Alternatively, you can soak the stained clothes overnight submerged in water with one cup of baking soda added. Wash, rinse, and check for odor. Hope this helps!!
Answer:
Weight=686.7N,
, S.G.=0.933, F=17.5N
Explanation:
So, the first value the problem is asking us for is the weight of methanol. (This is supposing there is a mass of methanol of 70kg inside the tank). We can find this by using the formula:
W=mg
so we can substitute the data the problem provided us with to get:
![W=70kg(9.81m/s^{2})](https://tex.z-dn.net/?f=W%3D70kg%289.81m%2Fs%5E%7B2%7D%29)
which yields:
W=686.7N
Next, we need to find the density of methanol, which can be found by using the following formula:
![\rho=\frac{m}{V}](https://tex.z-dn.net/?f=%5Crho%3D%5Cfrac%7Bm%7D%7BV%7D)
we know the volume of methanol is 75L, so we can convert that to
like this:
![75L*\frac{0.001m^{3}}{1L}=0.075m^{3}](https://tex.z-dn.net/?f=75L%2A%5Cfrac%7B0.001m%5E%7B3%7D%7D%7B1L%7D%3D0.075m%5E%7B3%7D)
so we can now use the density formula to find our the methanol's density, so we get:
![\rho=\frac{m}{V}](https://tex.z-dn.net/?f=%5Crho%3D%5Cfrac%7Bm%7D%7BV%7D)
![\rho=\frac{70kg}{0.075m^{3}}](https://tex.z-dn.net/?f=%5Crho%3D%5Cfrac%7B70kg%7D%7B0.075m%5E%7B3%7D%7D)
![\rho=933.33kg/m^{3}](https://tex.z-dn.net/?f=%5Crho%3D933.33kg%2Fm%5E%7B3%7D)
Next, we can us these values to find the specific gravity of methanol by using the formula:
![S.G.=\frac{\rho_{sample}}{\rho_{H_{2}O}}](https://tex.z-dn.net/?f=S.G.%3D%5Cfrac%7B%5Crho_%7Bsample%7D%7D%7B%5Crho_%7BH_%7B2%7DO%7D%7D)
when substituting the known values we get:
![S.G.=\frac{933.33kg/m^{3}}{1000kg/m^{3}}](https://tex.z-dn.net/?f=S.G.%3D%5Cfrac%7B933.33kg%2Fm%5E%7B3%7D%7D%7B1000kg%2Fm%5E%7B3%7D%7D)
so:
S.G.=0.933
We can now find the force it takes to accelerate this tank linearly at ![0.25m/s^{2}](https://tex.z-dn.net/?f=0.25m%2Fs%5E%7B2%7D)
F=ma
![F=(70kg)(0.25m/s^{2})](https://tex.z-dn.net/?f=F%3D%2870kg%29%280.25m%2Fs%5E%7B2%7D%29)
F=17.5N
