Answer:
1.2218 atm
Step-by-step explanation:
From ideal gas formula,
PV=nRT
Where n= number of moles
V= volume
T= temperature=25.0°C
= (273 + 25) = 298 K
R= gas constant = 0.082 l atm /K mol.
Making P subject of formula we have
P= [nRT] /V
Then substitute the values we have
P= [0.5 x 0.082 x 298] / 10
P= 1.2218 atm
A) tomatoes : chicken broth = 9:15 or 3:5
Tomatoes : spinach = 9:9 = 1:1
Spinach : chicken broth = 9:15 = 3:5
b) tomatoes : chicken broth = 4.5:7.5 = still 3:5
Tomatoes to spinach is still 1:1
Spinach : chicken broth 4.5:7.5 still = 3:5
Dividing all quantities by 2 doesn’t change the ratio.
Well, first you multiply 22×3 and then add the answer by 3!. whole times denominator plus numerator!
We know that
surface area of cylinder=2*[area of the base]+perimeter of base*height
area of the base=pi*r²
r=3 m
area of the base=pi*3²----> 28.26 m²
perimeter of the base=2*pi*r
r=3 m
perimeter of the base=2*pi*3----> 18.84 m
surface area=226.08 m²
226.08=2*[28.26]+18.84*h----> 18.84*h=226.08-2*28.26
18.84*h=169.56-------> h=169.56/18.84-----> h=9 m
the answer is
9 m
