Silver chloride is virtually insoluble in water so that the reaction appears to go to completion. How many grams of solid NaCl m
masya89 [10]

Answer:

0.535 g

Explanation:

The reaction that takes place is:

  • NaCl + AgNO₃ → AgCl + NaNO₃

First we <u>calculate how many AgNO₃ moles are there in 25.0 mL of a 0.366 M solution</u>, using the <em>definition of molarity</em>:

  • Molarity = moles / liters
  • moles = Molarity * liters

<em>Converting 25.0 mL to L </em>⇒ 25.0 / 1000 = 0.025 L

  • moles = 0.366 M * 0.025 L = 0.00915 mol AgNO₃

Then we <u>convert AgNO₃ moles into NaCl moles</u>:

  • 0.00915 mol AgNO₃ * \frac{1molNaCl}{1molAgNO_3} = 0.00915 mol NaCl

Finally we<u> convert NaCl moles into grams</u>, using its <em>molar mass</em>:

  • 0.00915 mol NaCl * 58.44 g/mol = 0.535 g

What force on Earth can affect the pull of gravity?
MakcuM [25]

Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass.

what is a mole and why does a mole of magnesium and a mole of carbon weigh different they have the same number of atoms?
timofeeve [1]
~ A mole is a unit of 6*10^23.

~One mole of carbon atoms has a mass of exactly 12 g.

~ Because magnesium atoms each have twice the mass of carbon atoms ( 24Mg compared with 12C), one mole of magnesium has a mass of 24 g.

~ Rather, one mole of any element has a mass in grams that is equal to its relative atomic mass.
