Answer:
The mass of the solute and the volume of the solution.
Explanation:
Hello,
In this case, given the formula of molarity:
In such a way, since the moles could not be directly measured, we must measure the mass of the solute and by using its molar mass, one could compute its moles. Moreover, since the solution is composed by the solvent (typically water) and the solute, we consequently must measure the volume of the solution needed for the preparation of such concentration-known solution. In such a way, we can actually prepare the required solution.
Best regards.
Answer:
As the garter snake can be found almost in any kind of habitat, what makes them be able to survive in any environment include:
1. They hibernate to increase their chances of survival in unfavorable weather conditions.
2. They can blend with the background of any environment especially grass to escape being eaten.
3. They produce an odor that is usually unpleasant especially when about to be attacked.
Explanation:
The garter snakes are distinguished by the three stripes running the length of their body and can often be found in forests, places that are even close to water bodies, and almost any place, even in holes.
Empirical formula of a compound gives the proportions of the elements in that compound but it does not define the actual arrangement and number of atoms.
Let the empirical formula of compound be 
.
The ratio of number of moles of C, H and O can be calculated as follows:
Simplifying the ratio,
Thus, the value of x, y and z will be 1, 2 and 1 respectively.
Therefore, the empirical formula will be 
.
Iron doesn't fit because it doesn't have enough atoms or protons in its nucleus so there for it belongs in column 2. <span />
From Charle's law the volume of a fixed mass of a gas is directly proportional to the absolute temperature at constant pressure.
Therefore';
V1/T1=V2/T2
Where; V1 = 2.40 l, T1 = 273 +20= 293 K, V2 = 4.80, and T2= ?
2.4/293= 4.8/T2
T2= (4.8×293)/2.4
= 586 K or 313° C
