In other words, if we use 0.15 moles of NaCl and add water to make the final solution volume of 1.5 liters, we know that the molar concentration of the final solution will be 0.1 M NaCl as specificied in the problem statement.utting this info into the equation above we arrive at the following: 0.1 M NaCl = (moles of NaCl) / (1.5 L of solution). Multipy both sides of this relation by 1.5 to clear this number from the right hand side and we arrive at the answer: Moles of NaCl = 0.15 moles of NaCl required to make this solution.
udev is the device manager for the Linux kernel. It manages device nodes in /dev and handles all user space actions when adding or removing devices.
In a way this naming scheme is similar to what is already done natively in udev for various device nodes via /dev/*/by-path/ symlinks. In many cases, biosdevname departs from the low-level kernel device identification schemes that udev generally uses for these symlinks, and instead invents its own enumeration schemes.
