Question

bronze analysis
moles of copper
the overall concentration of the copper(ii) in the solution is 0.00355 m.
how many moles of copper(ii) ions are in the 100.0 ml sample solution?
3.55 x 10⁻⁴ moles
0.355 moles
0.00355 moles
3.55 x 10⁻⁵ moles

Explanation:

Step1: Convert volume to liters

$100.0\ \text{mL} = \frac{100.0}{1000} = 0.1000\ \text{L}$

Step2: Calculate moles using $n=C\times V$

$n = 0.00355\ \text{mol/L} \times 0.1000\ \text{L} = 3.55 \times 10^{-4}\ \text{moles}$

Answer:

3.55 x 10⁻⁴ moles
