Using your knowledge of m/v = g/mL, you can start by putting that in the equation as:
And you know that the volume is 25 mL. So you could put this into the equation as:
And you also know that the molar mass of KCl is 74.55g (K = 39.1 g/mol and Cl = 35.45 g/mol. Add them together to get 74.55g/mol).
We can then put this in the equation as:
Then, we can mulitply them all together:
And now we know that
there are 0.01 moles of KCl in the sample.
When a cell is "at rest" it is in a state called the resting potential. In this state, neurons are more negatively charged ions inside the cell than outside the cell.
A homozygous trait is when both traits are the same size for example it could be AA or aa but not Aa

There are a lot of weird sleep-related world records out there. From the longest line of human-mattress dominoes—2016 'dominoes' and took 14 minutes for all of them to fall—to the most people served breakfast in bed at once—418 people in 113 beds set up on the lawn of a Sheraton Hotel in China. But there's one record that remains elusive: who holds the record for longest consecutive slumber?
Tough to call
The length of time someone is actually asleep is pretty tough to measure, which is what has kept the official title out of the hands of sleepers around the world. That doesn't mean, however, that there have been no valiant attempts—though they don't really count as real sleep.
In October of 2017, Wyatt Shaw from Kentucky fell asleep for 11 days. He was just seven years old and doctors ran several tests with no conclusive explanations. Wyatt did wake up with cognitive impairment, particularly when walking and talking, but made a full recovery after treatment with drugs typically used in seizure management.
In 1959, UK hypnotist Peter Powers put himself under a hypnotic sleep for eight straight days. It made quite the splash in European media and radio shows, but doesn't quite count as sleeping.
