3 0

Answer:

It is equal to Avogadro's number (NA), namely 6.022 x1023. If we have one mole of water, then we know that it will have a mass of 2 grams + 16 grams = 18 grams. Since we only have 0.001 grams, that means that we have NA * = 3.35*1019 molecules of water!

Explanation:

I'm just smart.

PSYCHO15rus [73]

From a chemistry book that I have read, it stated that Barium Sulfate is so insoluble in water. Due to this, it is not toxic to humans since it is not dissolved and absorbed by our body. In the other hand, Barium Carbonate is slightly soluble in water making it toxic to us.

 

Answer:

Barium carbonate is soluble in plain water

How many grams of sodium chloride are required to prepare 500.0 ml of a 0.100 m solution?
scoray [572]

Answer:

  • <u>2.92 g</u>

Explanation:

<u>1) Data:</u>

a) V = 500.0 ml = 0.500 liter

b) M = 0.100

c) mass = ?

<u>2) Formulae:</u>

a) Molarity: M = n / V

b) Number of moles: n = mass in grams / molar mass

<u>3) Solution</u>

a) M = n / V ⇒ n = M × V = 0.1000 M × 0.500 liter = 0.0500 mol

b) molar mass NaCl = 58.443 g/mol

c) mass = n × molar mass = 0.0500 mol × 58.443 g/mol = 2.92 g

Answer: 2.92 g
