х= 24

Step-by-step explanation:

According to the Alternate Interior angles theorem, the bottom left angle and the upper right angle have the same measure. Because they were formed from a pair of parallel lines crossed by a transversal one.

So, algebraically:

So, algebraically:

383.08

Step-by-step explanation:

Multiply 3 times 122 which is 366

Then multiply .14 times 122 which is 17.08

Then add.

The mass of allowable in the laboratory is 4599.5 grams

Explanation:

To calculate the volume of cuboid, we use the equation:

where,

V = volume of cuboid

l = length of cuboid = 14 ft

b = breadth of cuboid = 22 ft

h = height of cuboid = 9 ft

Putting values in above equation, we get:

(Conversion factor:

To calculate the moles of gas, we use the equation given by ideal gas which follows:

where,

P = pressure of the gas = 1.00 atm

V = Volume of the gas = 78503.04 L

T = Temperature of the gas =

R = Gas constant =

n = number of moles of hydrogen gas = ?

Putting values in above equation, we get:

Applying unitary method:

For every 109 moles of gas, the moles of present are 1 moles

So, for 3230.4 moles of gas, the moles of present will be =

To calculate the number of moles, we use the equation:

Moles of = 26.94 moles

Molar mass of = 170.73 g/mol

Putting values in above equation, we get:

Hence, the mass of allowable in the laboratory is 4599.5 grams
