Atomic mass=no of neutron+no of electron
Atomic mass=25+30
Atomic mass=55
<span>7.39 ml
For this problem, simply divide the mass of mercury you have by it's density.
100 g / 13.54 g/ml = 7.3855 ml
Since we only have 3 significant digits in 100., you need to round the result to 3 significant digits. So
7.3855 ml = 7.39 ml</span>
salt is not because it gets u dehydrated
Really? Really!?
IT'S SCIENCE!
