According  to  Avogadro constant   1  mole  =  6.02  x   10^23    what  about   9.25  x10  ^21

that  is    1  mole  x   (  9.25  x10  ^21)  /  (6.02 x10^23)  =  0.0154  moles

Suppose you wanted to know how many grams of KCl would be left if 350mL of
strojnjashka [21]

Answer:

52.2g of KCl would be left

The mass of KCl will remain despite the solution is been heated

Explanation:

When you are heating a solution, just the solvent (In this case, water), will be evaporated and, in theory, the mass of KCl will remain despite the solution is been heated.

Now, the mass of KCl that you can obtain from 350mL of a 2.0M solution will be:

<em>Moles KCl:</em>

350mL = 0.350L * (2.0mol / L) = 0.700 moles

<em>Mass KCl -Molar mass: 74.55g/mol-:</em>

0.700mol * (74.55g/mol) = 52.2g of KCl would be left

A beaker contains 175.32g of salt, NaCl(58.44g/mol). Water is added until the final volume is 2 liters. The solution should be d
cricket20 [7]

Answer:

E. 1.5M

Explanation:

because there is total 175.32 g of NaCl dissolved in 2 liter of water, and 58.44 g = 1 mol

so total miles = 175.32/58.32 = 3 moles

now 3 moles are in 2 liter of water, hence one liter contains 3/2= 1.5

Therefore answer is E. 1.5M

What effects do winds patterns have on climate
Nezavi [6.7K]

Prevailing winds bring air from one type of climate to another. For example, warm winds that travel over water tend to collect moisture as they travel; the water vapor in the air will condense as it moves into colder climates, which is why temperate coastal areas often receive heavy rainfall.

Hope it Helps! T^T
