Answer:

15.0L

Explanation:

p/v = constan

(9*21)/253 =(15v)/ 302

v = (9*21*302)/(15*253)

v=15.0

How many moles of solute are contained in a 250.0-milliliter solution that has a concentration of 0.85 M?
adoni [48]

Answer : The correct option is, 0.21 moles

Solution : Given,

Molarity of the solution = 0.85 M = 0.85 mole/L

Volume of solution = 250 ml = 0.25 L     (1L=1000ml)

Molarity : It is defined as the number of moles of solute present in one liter of the solution.

Formula used :

Molarity=\frac{\text{moles of solute}}{\text{Volume of solution in liters}}

Now put all the given values in this formula, we get the moles of solute of the solution.

0.85mole/L=\frac{\text{moles of solute}}{0.25L}

\text{moles of solute}=0.2125=0.21moles

Therefore, the moles of solute is, 0.21 moles

How many grams of Cl2 are in 0.345L at STP?
blsea [12.9K]

Answer: 1.09 g

Explanation:

If we use the approximation that 1 mole is 22.4 L, then setting up a proportion,

  • 1/22.4 = x/0.345 (x is the number of moles in the sample)
  • x = 0.0154 mol

Since the mass of a mole of chlroine is about 70.9 g/mol, (0.0154)(70.9) = 1.09 g (to 3 s.f.)
