Answer:
Molarity of potassium chloride is 0.100M
Explanation:
Molarity is defined as moles of solute per liter of solvent.
Moles of solute (Potassium chloride; MW: 74.55g/mol):
0.182g × (1mol / 74.55g) = <em>2.44x10⁻³mol KCl</em>
<em />
Liters of water using density are:
26.0g Water × ( 1mL / 1.071g) × (1L / 1000mL) = <em>0.0243L</em>
<em />
Thus, molarity of KCl in the sample is:
<em>2.44x10⁻³mol KCl / 0.0243L = </em><em>0.100M</em>
<em />

Answer: C(OCH2CH3)CHCClCH(CH)2
Explanation:
The structural formula for m-chlorophenyl ethyl ether is
C(OCH2CH3)CHCClCH(CH)2.
The structural formula shows the step-by-step linkages.
Melting point is dependent on the intermolecular forces which means the bonds between the molecules of bromine as it is a simple molecular structure the intermolecular bonds of bromine are weak bcz they are weak vandervaal forces thats why Bromines melting point is low..In short when intermolecular bomds are weak the M.P is lower
