4 0

Answer:

<u>Answer</u><u> </u><u>is</u><u> </u><u>9</u><u>.</u><u>2</u><u> </u><u>grams</u>

Explanation:

Molar mass of ethanol

{ \bf{CH _{3}CH_{2}OH}} = (12 \times 2) + (6 \times 1) + (16) \\  = 46 \: g

for moles:

{ \sf{1 \: mole \: of \: ethanol \: weighs \: 46 \: g}} \\ { \sf{0.2 \: moles \: weigh \: (0.2 \times 46) \: g}} \\  = 9.2 \: g

david’s mom wants to calculate how much it will cost to drive from los angeles, ca, to san francisco, ca. gas costs $4.00 a gall
grin007 [14]
She needs to know the distance from LA to SF.

Call that distance x. Then you can calculate the cost from:

# of gallons consumed: x miles / 38 miles/ gallon = (x/38) gallons

After that,

cost = # gallons * cost per gallon = (x/38) gallons * 4 $/gallon = 4x/38 $

What is the final volume?
zaharov [31]

Answer:

Option A. 9.4 L

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 8 L

Initial temperature (T₁) = 293 K

Final temperature (T₂) = 343 K

Final volume (V₂) =?

V₁ / T₁ = V₂ / T₂

8 / 293 = V₂ / 343

Cross multiply

293 × V₂ = 8 × 343

293 × V₂ = 2744

Divide both side by 293

V₂ = 2744 / 293

V₂ = 9.4 L

Therefore, the final volume of the gas is 9.4 L
