Question

the equation for molarity, m, is
where v is volume and n is the number of moles of solute.
m = \frac{n}{v}
a certain solution has a molarity of ( m = 3.46 , \text{mol/l} ) and has a volume of ( v = 0.770 , \text{l} ). what is the value of ( n )?
express your answer numerically in moles.

Explanation:

Step1: Rearrange molarity formula

$$n = M \times V$$

Step2: Substitute given values

$$n = 8.46\ \text{mol/L} \times 0.770\ \text{L}$$

Step3: Calculate the product

$$n = 6.5142$$

Answer:

6.51 mol (rounded to three significant figures, consistent with the given values)
