I don't really know this one can someone help its for my physical science class

What is the concentration of a solution that is made by diluting 50.0 mL of a 0.40 M NaCl solution to a final volume of 1000.0 m

Novosadov [1.4K]

Answer:

The correct answer is 0.020 M.

Explanation:

To solve this problem, we can use the equation M1V1 = M2V2, where M represents the molarity of the solution and V represents the volume of solution. Since we are given that the original solution is 50 mL and 0.40 M, these values are V1 and M1, respectively. The solution after dilution has a volume of 1000 mL, so this value is V2. We are solving for the molarity after dilution, which represents M2.

If we plug in the values specified above, we get the following:

M1V1 = M2V2

(0.40 M)(50.0 mL) = (M2)(1000.0 mL)

Solving for M2, we get:

M2 = 0.020 M

Notice that our answer has 2 significant figures because 0.40 has 2 significant figures, the least of any values given in the problem.

Therefore, the answer is 0.020 M.

Hope this helps!

What is the empirical formula for a compound if 300. 00 g of it is known to contain 82. 46224 g of molybdenum, 45. 741 g of chlo

maksim [4K]

the empirical formula for a compound is Mo2Br5Cl3.

The empirical components of a compound are the best entire quantity ratio of atoms of every detail within the compound. it's miles decided using statistics from experiments and therefore empirical. as an example, the molecular formula of glucose is C 6H 12O 6 however the empirical formulation is CH 2O.

An Empirical formula is the chemical components of a compound that offers the proportions (ratios) of the elements present in the compound however no longer the real numbers or arrangement of atoms. This will be the lowest complete range ratio of the elements within the compound.

The empirical method of a compound gives the only ratio of the range of various atoms gift, while the molecular formula gives the actual range of each distinctive atom found in a molecule. If the components is simplified then it is an empirical components.

There are two open cans of soda on the table.one can was just taken from the refrigerator and the other was taken from the cupbo

larisa [96]

The one in the cupbard looses its CO2 first as its warmer so its solution has a lower solibility to the CO2 gas

at lower temperatures the CO2 has less energy to escape from the solution of soda as CO2 in a solution is unstable it wants to be released

hope that helps <span />
