Ethylene glycol (C2H6O2) is used as an antifreeze in cars. If 250 g of ethylene glycol is added to 3.00 kg of water, what is the
Zepler [3.9K]

Answer:

2,909 M

Explanation:

molair mass is of.ethylene is 26,04 g/mol

first you need to calculate how much mL 3 kg is. You can do this by using the density of ethylene: 1,1 g/mL.

3000 g x 1.1 = 3300 mL = 3,3 L

Next you need to calculate the amount of moles:

250 g / 26,04 g/mol = 9,60 mol

Now you can calculate the molarity:

9,6/3.3 = 2,909 M

I don't know the answer for the second question. I'm sorry.

Determine how many oxygeng atoms are in 5.00 g of sample of sodium dichromate, na2cr2o7
vlada-n [284]

The number of oxygen atoms is in 5.00 g of sample of sodium dichromate, Na₂Cr₂O₇ is 1.125 x 10²³ atoms.

<h3>What is sodium dichromate?</h3>

Sodium dichromate is an inorganic compound. It is sued in tanning and mental illness.

The molar mass of sodium = 23 gm

The molar mass of Cr = 51.99 gm

The molar mass of oxygen = 16 gm

Molar mass of Na₂Cr₂O₇ = 2(23) + 2(51.99) + 7(16) = 261.98 gm

Number of moles in 7 gm = mass / molar mass = 7 / 261.98 = 0.0267 moles

1 mole of  Na₂Cr₂O₇ contains 7 moles of oxygen, therefore:

The number of moles of oxygen in 0.0267 moles = 0.0267 x 7 = 0.1869 moles

Thus, the number of atoms = 0.1869 x 6.02 x 10^23 = 1.125 x 10²³ atoms.
