Answer:

C. 22L

Step-by-step explanation:

STP is 273 K and 1 atm

Remember that R=0.0821 atm*L/mol*K

Put this into ideal gas law and solve for volume

PV=nRT → V=nRT/P

V=[(1mol)*(0.0821 atm*L/mol*K)*(273 K)]/(1 atm)

V=[22.4133 atm*L]/(1 atm)=22.4133 L

So the answer is 22 L

-8x + 18 - 18 > -22 - 18

-8x / -8 > -40 / -8

Help pleaseeeeeeeeeeeeee!!!!!!!!!!!!!!!! T^T

1 + (-5/8) = 3/8

Explanation: If the coffee wasn’t drank it would’ve been at fraction 1 (or 100%)

Since he drank 5/8 of it. The coffee left is now 1-(5/8)

But since the question has asked to give the equation in addition format. Put a plus sign in between the two.

Therefore,
1 + (-5/8)

Solve it,
= 1-(5/8)
= (8-5)/8
= 3/8

Hence the equation is:

1 + (-5/8) = 3/8.

Express each ratio as a unit rate. 325.4 miles on 17.3 gallons<br><br><br><br> having trouble :/
kkurt [141]
Hello! I can help you with this question! To find the unit rate, we’ll have to divide total by number of units. Or in this case, miles/gallons. 325.4/17.3 is 18.809 and other numbers, or 18.81 when rounded to the nearest hundredth. If you’re looking for the answer to the nearest hundredth, the answer is 18.81 mpg. Or, if you’re looking for the answer to the nearest whole number, the answer is 19 mpg.
