To calculate the molarity you only need to know the number of moles in the solution and the volume of that solution. This exercise gives both and with that you divide moles by volume(usually in liters).
500 ml equals 0,5 L
molarity= number of moles/ volume
molarity=0,75 x 0,5
= 0,375 mol/L
Isotopes are elements that differ in the number in neutrons while the numner of protons are the same. The answers of the questions are: 1) 18/8 O 2) 22/10 Ne 3) 53/25 Mn 4) 37/24 Cr 5) 106/81 Ti.
The one with feather. because it was probably form the Dino era
Converting the temperature, 295 K from Kelvin to Celsius scale:
Water has a boiling point of 
and a melting point of 
When we compare water at two different temperatures, 
we can say that water is in liquid form at both these temperatures as both of them are quite below the boiling temperature and above the melting temperature.
The temperature difference between water at the given two temperatures = 
Water at 
is at a higher temperature and so is warmer than water at a lower temperature of 
.
Eating too much lipids is hazardous to the health. It has a lot of negative effects. One is cardiovascular complications, too much of lipids can cause high blood cholesterol, arterial hardening, heart diseases and stroke. Also, obesity is possible. Eating too much lipids is associated with metabolism abnormalities.
