What is the molarity of a solution with a volume of 974 ml containing 17 g of cuso4
?
a. 0.109m cuso4
b. 9.66m cuso4
c. 2.79m cuso4
d. 0.0001m cuso

There are a number of ways to express concentration of a solution. This includes molarity. Molarity is expressed as the number of moles of solute per volume of the solution. The concentration of the solution is calculated as follows:

Molarity = 17 g (1 mol / 159.61 g) / 974 mL (1 L / 1000 mL)

Molarity = 0.109 M

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
