Answer: m = 3.3 mol·58.326 mol = 192 g

Step-by-step explanation: molar mass of substance is

M= (24.31+ 2·1.008 + 2·16) g/mol = 58.326 g/ mol.

Amount of substance n = m/M and mass m = n·M

Answer:

192 cm3

Step-by-step explanation:

The volume of any pyramid is 1/3 × b × h, where b =  area of base of the pyramid and h = height of the pyramid.

  • In this case, the dimensions for the base are 6 and 8.
  • The height is 24

Area of Base:

  • \frac{6*8}{2}
  • 48/2
  • 24

Now, we multiply 24 by 24.

  • 24*24
  • 576

Lastly, we divide by 3.

  • 576/3
  • 192

Therefore, the answer is 192 cm^3.

Which option equals tan 40°? Select all that apply.
AlladinOne [14]
Answers
(sin40)/(cos40)  and 
(cos50)/(sin50)

Explanations
Tangent is a trigonometric ratio given by,
tan = opposite/adjacent.
lets take,
x⇒adjacent
y⇒opposite
h⇒hypotenuse

tanФ=y/x
sinФ=y/h  and 
cosФ=x/h

(sinФ)/(cosФ) = y/h ÷ x/h
                      =y/h×h/x
                      =y/x
This shows that
(sinФ)/(cosФ) = tanФ

We also know that,
sinФ = cos(90-Ф). So,
sin40 = cos(90-40) =cos50

So therefore;

tan40 = (sin40)/(cos40) = (cos50)/(sin50)
