Answer:
2 moles of C-12 have 24g mass
Explanation:
Given data:
Number of moles of C-12= 2 mol
Mass of C-12 = ?
Solution:
Formula:
Number of moles = mass / molar mass
Molar mass of C-12 = 12 g/mol
Now we will put the values in formula.
2 mol = mass / 12 g/mol
Mass = 2 mol × 12 g/mol
Mass = 24 g
Thus 2 moles of C-12 have 24 g mass.

Composition of Stainless Steel
Steel is an alloy of iron and carbon. Stainless steels are steels containing at least 10.5% chromium, less than 1.2% carbon and other alloying elements
By stirring and increasing temperature, there is an increase in dissolving capacity of the solid solute.
<u>Explanation:</u>
If a solute is added to the solution, it doesn't get dissolve easily then we have to increase the temperature, which in turn increases the movement of the solvent (may be water) and the solute particles, thus increases the dissolving power of the solid solute. One more way is by constant stirring, that is by making more contact among the solvent as well as the solute particles there by increasing the solubility of solid solute.
