Using float to place an element in the right side with CSS - html

Question

I'm trying to do a nav bar with a contact button stuck to the right of the page. I want contact to be aligned with the rest of the elements of the nav bar, however when I add float: right; it just disaligns my nav bar and it doesn't move contact to the right.
Here you can see my code: http://jsfiddle.net/LG2vR/19/
Can someone please tell me the proper way to accomplish this please?
Thanks!

Am not sure if this is what you need exactly, see the updated fiddle

Basically, i have used position absolute to move your last child of the navigation to the right side and increased width of the navigation till the end of the header.
nav {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100px;
padding: 10px 100px;
z-index: 500;
box-sizing: content-box;
transition: .3s;
background: red;
}
nav.white {
background: white;
height: 35px;
padding: 10px 100px;
transition: .5s;
}
nav ul {
list-style: none;
float: left;
margin: 0;
padding: 0;
display: flex;
width: 90%;
position: relative;
}
nav ul li {
list-style: none;
}
nav ul li:last-child {
display: inline-block;
right: 5%;
position: absolute;
top: 0;
}
nav ul li a {
line-height: 80px;
color: #FFFFFF;
margin: 12px 30px;
text-decoration: none;
text-transform: capitalize;
transition: .5s;
padding: 10px 5px;
font-size: 16px;
}
nav ul li a:hover {
background-color: rgba(255,255,255,0.2);
}
nav.white ul li a {
color: #000;
line-height: 40px;
transition: .5s;
}
nav ul li a:focus {
outline: none;
}
<div class="wrapper">
<nav>
<ul>
<li>LOGO</li>
<li>Home</li>
<li>Page 1</li>
<li>Page 2</li>
<li><a class="contact" href="#">Contact</a></li>
</ul>
</nav>

Answer 2

Just add:
nav ul li a {
float: left;
}
right before:
nav ul li a.contact {
float: right;
}
or use flexbox!

.wrapper li {list-style-type: none;}
.wrapper {
overflow: hidden;
background-color: red;
}
.wrapper .logo{
margin-right : 30px;
}
.wrapper a {
float: left;
color: #f2f2f2;
text-align: center;
padding: 14px 16px;
text-decoration: none;
font-size: 17px;
}
.wrapper a:hover {
background-color: #ddd;
color: black;
}
.wrapper a.active {
background-color: #4CAF50;
color: white;
}
.topnav-right {

<div class="wrapper">
