At 0.918 atm and 56.3 ºC a sample of gas occupies 116.9 L. What volume does it occupy at 0.114 atm and 1.6 ºC

1 answer:

5 0

PV=nRT since we are only using P,V, and T we have the relationship

PV=T then PV/T=k now we can compare the two conditions...

0.114V/1.6=0.918(116.9)/56.3

V=(1.6*0.918*116.9)/(56.3*0.114)

V≈26.75 L

A spherical cantaloupe is cut in half. The visible cross-section has an area of 5252 in2. The volume of the cantaloupe is _____

artcher [175]

Answer:

V = 286319.465 cm3

Step-by-step explanation:

First, you have to find the radius to be able to find the volume of a sphere.

The equation for the area of a circle is pi r^2 so you have to so some algebra.

5252 = pi r ^2

5252/pi = r^2

1671.76352 = r^2

sqrt(1671.76352) = r

r = 40.8872048

then you do the equation for the volume of a circle which is 4/3 pi r^3

4/3 pi (40.8872048)^3

4/3 pi 68353.7373

4/3 214739.599

286319.465

V = 286319.465 cm3

Simplify 7 1/3t−(10 2/3t−6) pls

Flura [38]

Answer:

$-\frac{10t}{3}+6$

Step-by-step explanation:

$7 \frac{1}{3}t-(10 \frac{2}{3} t-6)$

Convert $7\frac{1}{3}$ to a mixed number

$7\frac{1}{3}=\frac{7\cdot 3+1}{3}$

$=\frac{22}{3}$

$\bold{\frac{22}{3}t-\left(10\frac{2}{3}t-6\right)}$

Convert $10\frac{2}{3}$ into a mixed number

$10\frac{2}{3}=\frac{10\cdot 3+2}{3}$

$=\frac{32}{3}$

$\bold{\frac{22}{3}t-\left(\frac{32}{3}t-6\right)}$

$=\frac{22t}{3}-\frac{32t}{3}+6$

$\bold{=\frac{-10t}{3}+6}$

Terms

Follow the PEMDAS order of operation:

P = Parenthesis
E = Exponents
M = Multiplication
D = Division
A = Addition
S = Subtraction

You do these steps in the order for which the equation comes. For example, start with the exponents if there are not any parentheses.
