What is the molarity of a dolution in which 5.6 moles of sodium nitrate is dissolved in water to a final volume of 4.9l

Molarity of the given solution is 1.14 M

Explanation:

Molarity of a solution = (Number of moles of solutes)/(volume of solution in litre)

Here solute is sodium nitrate and solvent is water.

Total volume of solution is 4.9 L.

So molarity of solution = (5.6 moles)/(4.9 L) = 1.14 M

Molarity of a solution is the moles of solute present in 1 L solution.

Given the moles of sodium nitrate = 5.6 mol

Volume of solution = 4.9 L

Molarity of the solution =

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
