We first assume that this gas is an ideal gas and we use the ideal gas equation to determine the answer. It is expressed as:

PV = nRT

Molar volume can be obtained from the equation by V/n.

V/n = RT/P

Therefore, the correct answer from the choices listed above is option A, <span>at 273 K and at 2.0 atm.</span>

The quadrilateral is a rhombus.<br> If EF = 13 and DF = 18, find EH to the nearest tenth.
-Dominant- [34]

Answer:

EH = 9.4

Step-by-step explanation:

A rhombus is a quadrilateral with equal length of sides.

Given that,  EF = 13 and DF = 18

⇒ DH = HF = \frac{18}{2}

             = 9

The property that the diagonals of a rhombus are at right angle to each other.

Thus, applying the Pythagoras theorem, we have;

/hyp/^{2} = /adj1/^{2} + /adj2/^{2}

(EF)^{2} = (EH)^{2} + (HF)^{2}

(13)^{2} = (EH)^{2} + (9)^{2}

169 =  (EH)^{2} + 81

(EH)^{2} = 169 - 81

           = 88

EH = \sqrt{88}

      = 9.381

The length EH is 9.4
