Calculate the molarity of 13.1 g of NaCl in 727 mL of solution
valentina_108 [34]

Answer:

The molarity of the solution is 0,31 M

Explanation:

We calculate the weight of 1 mol of NaCl from the atomic weights of each element of the periodic table. Then, we calculate the molarity, which is a concentration measure that indicates the moles of solute (in this case NaCl) in 1000ml of solution (1 liter)

Weight 1 mol NaCl= Weight Na + Weight Cl= 23 g + 35, 5 g= 58, 5 g

58, 5 g-----1 mol NaCl

13,1 g ---------x= (13,1 g x 1 mol NaCl)/58, 5 g= 0, 224 mol NaCl

727 ml solution------ 0, 224 mol NaCl

1000ml solution------x= (1000ml solutionx0, 224 mol NaCl)/727 ml solution

x=0,308 mol NaCl---> <em>The solution is 0,31 molar (0,31 M)</em>

A flask contains Ne at 542 mmhg together with At at 234 mmHg. What will the total pressure be?
sineoko [7]

Answer:

The total pressure will be 1, 021 atm

Explanation:

We apply Dalton's law, where for a gas mixture the total pressure is the sum of the partial pressures of each gas that makes up that mixture. The unit of pressure is converted into atm:

760mmHg----1 atm

542mmHg----x=(542mmHgx 1 atm)/760mmHg=0,713 atm

234mmHg----x=(234mmHgx 1 atm)/760mmHg=0,308 atm

Pt=P Ne + P At= 0,713 atm + 0,308 atm= <em>1, 021 atm</em>
