Molarity is the number of moles of solute in one liter of solution whereas molality is the number of moles of solute present in 1 kilo gram of solution.
Molarity is denoted by M and molality denoted by m
Mass of solution
Density of solution = 1.1 g /mL
d = 1.1 = (W_B + W_A) /V
V = 910.11 mL
molarity of solution is:
= 0.0433 /0.910 = 0.0474 M
Thus, moalrity of solution is 0.0474 M
Answer:
The alkali metals are the highly electropositive metals. Highly electropositive metals cannot be extraction carbon reduction process, because these metals do not react with carbon
Explanation:
Answer:
Vast Territory
Explanation:
Russia is a very big area. It makes sense that some parts vary in their climate.
To determine the mass of xenon tetrafluoride, we need to know first the number of fluorine atoms present in <span>oxygen difluoride. We need to convert first the mass into moles then make use of the relation of the elements from the chemical formula. Then, use the avogadro's number to convert it to number of atoms. Then, we do the reverse of the steps above but this time for </span><span>xenon tetrafluoride.
25.0 g OF2 ( 1 mol / 54 g ) ( 2 mol F / 1 mol OF2 ) ( 6.022 x10^23 atoms F / 1 mol F ) ( 1 mol / 6.022x10^23 atoms) ( 1 mol XeF4 / 4 mol F ) (207.3 g / 1 mol XeF4) = 47.99 g XeF4</span>
